abstract = {To take advantage of the data generated in buildings, this document proposes a methodology based on a machine learning model to improve thermal comfort and energy efficiency. This methodology uses measured data (e.g., indoor/outdoor temperature, relative humidity, etc.) and forecast data (e.g., meteorological data) to train a multiple linear regression model to forecast the indoor temperature of the space under study. Using the genetic algorithm optimization method, this model is then used to evaluate the different heating strategies generated. For each strategy, a score is assigned according to user-defined criteria in order to prioritize them and select the best one. By studying an office building simulated under the TRNSYS software, a multiple linear regression model was implemented with errors less than 1% and an adjusted R2 coefficient close to 0.9. Compared to a conventional heating strategy, this methodology can improve thermal comfort by up to 43%.},

abstract = {The non-continuity of the drying process after sunset is one of the most significant limitations with solar dryers that has an impact on product quality and drying time. To overcome this problem, we installed a Thermal Energy Storage (TES) unit in an indirect solar dryer. Given the economic advantages offered by Sensible Heat Storage (SHS) systems and their availability, they are the best option to consider in a drying application. In this paper, we investigated a SHS unit integrated within a solar dryer under real meteorological conditions in eastern Morocco. The solar dryer with a storage system was simulated using the Computational Fluid Dynamics (CFD) approach, which was validated using experimental data from the literature. The research is mainly focused on the amount of material required, the proper porosity of the packed bed, and the overall performance of the solar dryer for various types of SHS materials. The obtained results proved that when compared to the case without storage, the efficiency of the solar dryer with sensible heat storage increased by about 2.47% at night. Regarding the study of different materials, granite stones showed better performance with a porosity of 40% and a packed bed thickness of 15 cm, where the temperature differences between the two cases with and without storage reached almost 5° at night.},

It is thus essential to analyze the thermal behavior at the hollow block’s level in order to better understand the temperature and heat flux distribution in its structure and potentially limit as much as possible the heat transfer through the block.In this scope, this paper offers an experimental and numerical in-depth analysis of heat transfer phenomena inside a hollow block using a dedicated experimental setup including a well-insulated reference box and several thermocouples and fluxmeters distributed at the boundaries and inside the hollow block. The block was then numerically 3D modelled and simulated using COMSOL Multiphysics under the same conditions, properties, and dimensions as the experimentally tested block. The comparison between the numerical and experimental results provides very satisfactory results with relative difference of less than 4% for the computed thermal resistance.},

abstract = {To promote the development of thermal energy storage (TES), the sodium acetate trihydrate (SAT) presents interesting thermal properties. However, this material may suffer from aging throughout thermal cycles. Various solutions were explored in the literature to limit this aging, mainly based on the use of additives such as water. In this study, two samples were prepared. The first one consisted of raw SAT material whereas 3 wt.% of supplementary water has been added to the second one. They were then poured into 350 cm3 bricks, which were placed in an experimental test bench. After 35 cycles between 20 and 70 °C, a drop of about 10% of the latent heat was observed for the first sample. This behavior was like the literature data. For the second sample, the decrease of latent heat was more rapid (about 30%). Contrary to our expectations, the water addition seems not beneficial for the improvement of thermal stability. Interestingly, we noticed that the drop of the latent heat was fully reversible after sample stirring. This degradation might not be related to a thermal destructive mechanism but rather to a global segregation phenomenon. This segregation may be due to the breaking of hydrogen bonding between anhydrous sodium acetate and water, resulting in the separation of the two species.},

abstract = {Phase change material (PCM) experiencing supercooling and phase change hysteresis are widely reported in the literature. However, only few studies model analytically such PCM, and they mostly focus on either supercooling or phase change hysteresis, but rarely on both phenomena. Moreover, partial phase change cycles, with an incomplete melting or solidification, are rarely considered even if these processes occur frequently in latent heat thermal energy storage (LHTES) systems. The objective of this study is to model analytically the thermal behaviour of a PCM experiencing supercooling and phase change hysteresis, for complete and partial phase change cycles. The developed method, based on a heat source term, enables to model the recalescence process during the solidification. Currently rarely considered, the influence of the cooling rate on the supercooling degree and the recalescence process is evaluated with a phenomenological approach. For partial cycles, the different behavior between heating and cooling is modelled with the hysteresis model “curve scale” already validated in literature. The experimental validation is carried out on a PCM brick sample, monitoring both the heat flux and the PCM temperature, which enables to characterize a greater mass of PCM compared to direct scanning calorimeter (DSC) analysis. The selected PCM undergoing supercooling during solidification is PEG6000, a polymer suitable for domestic hot water (DHW) storage. Results show a good agreement between experimental and numerical results for complete heating and cooling cycles. The behavior laws used to model the solidification with the supercooling and recalescence processes are validated for the cooling rate range tested. The modelling is also satisfactory concerning the experiments on partial solidification for different temperature plateaus. However, the model fails to correctly represent the thermal behavior for a cooling process after a partial melting of the PCM. To conclude, the developed model enables to represent accurately the thermal behaviour of a PCM experiencing supercooling and phase change hysteresis for most of the phase change processes studied. Investigations on the thermal conditions influencing the crystalline structure and the effect on the phase change dynamic are suggested to improve supercooling modelling. The developed model needs to be validated for PCM having a higher supercooling degree, such as sugar alcohols or salt hydrates.},

abstract = {An experimental set-up of triple-glazed supply-air window is developed in this research in order to characterize the window’s thermal performance without solar radiation. By simultaneously measuring the local temperatures and heat fluxes with thermocouples and heat fluxmeters, the heat fluxes determination requires no longer using the correlations of heat transfer coefficients around the window, which are often the source of high uncertainties. Results show that the use of fluxmeters brought a more accurate measure of heat transfers around and in the window. Thereafter, the heat transfer coefficients can be correctly estimated by empirical evidence. Uncertainty analysis is then presented to highlight the reliability of the experimental method. Afterwards, the obtained experimental data are compared with those of numerical model developed by using Fluent® software. A thorough comparison analysis is provided to explain which parameters play a role in deviating the results between the two methods, leading to conclude the validity of numerical model assumptions with respect to the real conditions of experimental set-up.},

abstract = {Tunnel face stability constitutes a significant challenge for shield tunneling in urban areas. The use of a slurry pressure balanced shield machine in mixed ground conditions containing mudstone is generally disturbed by clogging, which results in noises and large fluctuations in the tunnel face pressure. These fluctuations add difficulties to the prediction of the slurry pressure. This paper proposes a denoising method to overcome this difficulty. This method is combined with variational mode decomposition and detrended fluctuation analysis. The method is coupled with cross-correlation analysis (CCA) and a long short-term memory (LSTM) network to predict the tunnel face pressure using both tunneling parameters and geological data as input. The paper proposes a predictive strategy that separates the trend component and fluctuation component from the denoised tunneling data via CCA. Two LSTM-based predictors are presented and combined for the development of a new modeling strategy. The performances of the proposed strategy are illustrated through an application to the Nanning metro. The LSTM model with the proposed strategy gave excellent results in both mudstone and round gravel grounds with an overall R2 value of 0.9974. The paper also presents a comparison of the proposed model with some traditional models as well as a discussion on the importance of input features in different ground conditions.},

They are employed in the construction of building walls in order to optimize thermal-energy-storage and maintain human comfort temperature. However, large numbers of competitive materials available, with each having its own thermophysical properties, the decision for selecting a suitable PCM involves several evaluation criteria. In this paper, a methodology is proposed to allow the decision maker to analyze, evaluate and select the best PCM according to different criteria. Five PCMs are compared in terms of thermal performance by using Analytic Hierarchy Process (AHP) method. After this process, the obtained ranking was verified by using a simulation model and the actual thermophysical properties of the PCMs in the region of Marrakech during summer season. As a result, it turns out that the outputs of AHP are in good agreement with those obtained with the simulation model. Additionally, the BioPCM-Q23 is ranked first in terms of thermal performance. The simulation results indicate that the recommended position for the PCM layer should be at the interior surface, when it is placed after the isolator. Also, the proposed configuration can ensure a comfortable indoor climate with an indoor temperature around 23.5 ℃. Plus, it provides the same energy performance with a decrease in the thickness of the PCM by 1.5 cm, which significantly helps to save energy.},

abstract = {Improving the energy efficiency of the building sector has become an increasing concern in the world, given the alarming reports of greenhouse gas emissions. The management of building energy systems is considered an essential means for achieving this goal. Predicting indoor temperature constitutes a critical task for the management strategies of these systems. Several approaches have been developed for predicting indoor temperature. Determining the most effective has thus become a necessity. This paper contributes to this objective by comparing the ability of seven machine learning algorithms (ML) and the thermal gray box model to predict the indoor temperature of a closed room. The comparison was conducted on a set of data recorded in a room of the Laboratory of Civil Engineering and geo-Environment (LGCgE) at Lille University. The results showed that the best prediction was obtained with the artificial neural network (ANN) and extra trees regressor (ET) methods, which outperformed the thermal gray box model.},

It combines the adjusted weighted arithmetic water quality index method (AWAWQIM), a close-ended questionnaire, and step-wise assessment ratio analysis (SWARA) to develop groundwater potability (PoGWQI) and palatability (PaGWQI) indices. Both a geographic information system (GIS) and the kriging interpolation method (KIM) are employed to create spatiotemporal mapping of PoGWQI and PaGWQI. The research is based on data from 79 wells, which were provided by the Palestinian Water Authority (PWA). Data include fecal coliform (FC), nitrate (NO3), pH, chloride (Cl), sulfate (SO4), bicarbonate (HCO3), total dissolved solids (TDS), turbidity, and hardness. Results indicate that 2% and 5% of water samples were unpotable and unpalatable, respectively. Unpotable samples were found in areas with poor sewer networks and intensive use of agrochemicals. All groundwater samples (100%) in the eastern part of the West Bank were unpalatable because of seawater intrusion. Unconfined aquifers were more vulnerable to potability and palatability contamination. It was noticed that PoGWQI is sensitive to FC and NO3, while PaGWQI is sensitive to HCO3, TDS, and Cl. Consequently, these quality parameters should be monitored well. The proposed method is of great interest to water decision-makers in Palestine for establishing strategies to protect water resources.},

abstract = {This study presents an experimental comparison of three characterization methods for phase change materials (PCM). Two methods were carried out with a calorimeter, the first with direct scanning (DSC) and the second with step scanning (STEP). The third method is a fluxmetric (FM) characterization performed using a fluxmeter bench. For the three methods, paraffin RT58 and polymer PEG6000, two PCM suitable for domestic hot water (DHW) storage, were characterized. For each PCM, no significant difference was observed on the latent heat and the total energy exchanged between the three characterization methods. However, DSC and STEP methods did not enable the accurate characterization of the supercooling process observed with the FM method for polymer PEG6000. For PEG6000, the shape of the enthalpy curve of melting also differed between the experiments on the calorimeter—DSC and STEP—methods, and the FM method. Concerning the PCM comparison, RT58 and PEG6000 appeared to have an equivalent energy density but, as the mass density of PEG6000 is greater, more energy is stored inside the same volume for PEG6000. However, as PEG6000 experienced supercooling, the discharging temperature was lower than for RT58 and the material is therefore less adapted to DHW storage operating with partial phase change cycles where the PCM temperature does not decrease below 52 °C.},

This issue is critical because water leakage causes economic losses, damages to the surrounding infrastructures, and soil contamination. Progress in real-time monitoring of WDS and ML has created new opportunities to develop data-based methods for water leak localization. However, the managers of WDS need recommendations for the selection of the appropriate ML methods as well their practical use for leakage localization. This paper contributes to this issue through an investigation of the capacity of ML methods to localize leakage in WDS. The campus of Lille University was used as support for this research. The paper is presented as follows: First, flow and pressure data were determined using EPANET software; then, the generated data were used to investigate the capacity of six ML methods to localize water leakage. Finally, the results of the investigations were used for leakage localization from offline water flow data. The results showed excellent performance for leakage localization by the artificial neural network, logistic regression, and random forest, but there were low performances for the unsupervised methods because of overlapping clusters.},

abstract = {The integration of new building materials incorporating phase change material (PCM) into the building envelope leads to an increase of the heat storage capacity, which may have an influence on minimizing the cooling demand and heating of the building. This work addresses a thermal performance enhancement of brick walls with incorporated PCMs. The improvement has been assessed through a numerical approach in dealing with a one-dimensional transient conduction problem with phase change, while leaning on experimental results from a transient guarded hot plates method. The simulations have been fulfilled using a hybrid method combining both the finite volume method (FVM) and an enthalpy porosity technique. The results of this combined approach are in good agreement. In the light of the findings obtained, it appears that PCMs' incorporation into a brick masonry can both reduce peak temperatures up to 3°C and smooth out daily fluctuations. Thereby, the evaluation achieved can turns out useful in developing brick walls with an incorporated PCM for passive cooling, thus improving buildings' thermal performance.},

abstract = {Open storage yards at industrial sites usually comprise several piles of granular materials, representing a particulate matter source that may significantly deteriorate air quality. The aeolian erosion of stockpiles is affected by changes in airflow patterns due to the pile shape and the presence of nearby piles or buildings. The aim of this study was to analyse the impact of wind erosion of successive parallel stockpiles on flow behaviour and particle emissions. A wind tunnel experiment was conducted in six configurations: one isolated pile and two successive piles separated by gaps of 0.9h and 1.8h (h is the pile height) oriented to 60$,^circ$and 90$,^circ$with respect to the main wind flow direction. The particles in the piles had a bimodal particle size distribution consisting of sand that was erodible (white) and non-erodible (black) in the investigated velocity range. The contrasting colours enabled the visualisation of the non-erodible sand accumulation. The mean field of the wall shear stress distribution and flow pathlines predicted by numerical simulation were associated with the experimental erosion patterns. The emitted mass was experimentally quantified as the difference between the initial and final stockpile weights. Downstream pile had a large impact on the aeolian erosion as it was highly eroded as a result of the impact of the particles emitted from the upstream pile. The emissions of the two consecutive stockpiles were greater than twice the emissions from an isolated stockpile for both orientations. Additionally, emissions were lower for configurations in which the piles were perpendicular.},

No numerical model of the composite solar wall is currently available in the Dymola/Modelica software library. The first objective of this work is to develop one such model. The article describes the elementary components, along with the equations that allow modeling the heat transfers and storage phenomena governing both the thermal behavior and performance of the solar wall. This model was built by assembling various existing basic elements from the software’s “Building” library (e.g., models of heat transfer by convection, radiation and conduction) and then creating new elements, such as the storage element incorporating the phase change material (PCM). To validate this solar wall model, numerical results are compared to experimental data stemming from a small-scale composite solar wall manufactured in our laboratory, and the experimental set-up could be tested under real weather conditions. After verifying the level of confidence in the model, the energy performance of two solar walls, one with a conventional storage wall (sensible heat storage) the other containing a PCM (the same as in the experiment), are compared. The result indicates that the solar wall incorporating a PCM does not in this case release any more energy in the room to be heated.},

A first validation of the numeric resolution algorithm of the preliminary model was realised. Then the model was supplemented by considerations related to the characteristics of the selected plants: ivy and Virginia creeper, such as the semi-transparent appearance of foliage plants and their geometric distribution. The numerical prediction was very close to the experimental values, and the mean error was about 1 °C. This difference makes it possible to validate the developed model.},

abstract = {Phase change materials, such as sodium acetate trihydrate, are efficient materials for Latent Heat Thermal Energy Storage (LHTES) according to their interesting thermal properties (high latent heat and specific heat). Their main drawback is a large degree of supercooling, up to 90 K for sodium acetate trihydrate, where the material may remain liquid below its melting point. However, heat could be released if the solidification could be triggered. For a better understanding of how heat is discharged after an initial cooling by external water flow and a solidification induction by seeding, the temperature was experimentally recorded to measure the residual solidification plateau duration. This experiment was repeated for different nucleation temperatures and fit well with the theoretical predictions. An increase of 90% in the solidification duration was observed when the supercooling degree dropped from 35 to 8 K. Thanks to an original experimental bench, this temperature record has been compared with a fully new method allowing the measurements of the material's opacification throughout the solidification process. Finally, two different opacification behaviors were observed for supercooling degrees below and above 20 K.},

abstract = {Modelling of latent heat thermal storage systems is mainly achieved with an analytical formulation describing the thermodynamic state of the phase change material (PCM). In literature, different models exist to describe the evolution of the liquid fraction, the effective heat capacity and the enthalpy as a function of temperature. The main issue is to correctly establish these behaviour laws and to identify the thermophysical properties of each PCM. Analytical models proposed in literature often have obvious limitations, such as the presence of discontinuities or the impossibility to represent asymmetric phase change dynamics. Such approaches a priori do not allow to model accurately the thermodynamic behaviour of the PCM. Given the limitations identified on existing models, a new analytical model is proposed in this paper. Moreover, it is not uncommon to observe the presence of two heat flux peaks during the phase change process of a PCM, as with the studied PCM (RT58). Therefore, we propose a method to model the two heat flux peaks, which are rarely considered in literature. PCM properties are determined thanks to a four-step identification process, using experimental data and the different analytical models studied. Based on the numerical modelling of the rectangular container used for the experiments, and on the identified thermodynamic properties of the enclosed PCM, a comparative study between the new analytical model and existing models is carried out. It appears that modelling only a single heat flux peak is not satisfactory for the studied PCM, and taking into account a second heat flux peak decreases the error on the exchanged energy by a factor of 2.5 to 6.5 depending on models. The new model leads to an accuracy gain of a factor of 1.5 to 3.3 compared with existing models. We do not recommend the model based on a linear evolution of the liquid fraction as the resulting error is between 1.6 and 3.3 times greater than for the other models. The study carried out is based on both melting and solidification processes, and concerns a PCM which does not undergo supercooling.},
