abstract = {The determination of both the thermal and thermodynamical properties of a composite material containing phase change material is done thanks to an inverse method, which combines experimental measurements and numerical computations. Given first an in-house experiment, which allows us to test samples at a macroscopic scale (i.e., close to the real conditions) and to set various types of thermal stresses, and secondly the simulation of the corresponding thermal behavior, relying on an accurate thermodynamical modeling and taking into account the real operating parameters (e.g., thermal contact resistances and non-symmetric heat fluxes on each side), it is possible to characterize the solid and liquid thermal conductivities and heat capacities, as well as the temperature range associated with a non-isothermal phase transition and the associated latent heat. The specificity of the present approach is to allow, in a single step, a characterization of all the involved thermo-physical parameters that are usually required in simulation tools (e.g., EnergyPlus…). Moreover, the hitherto studies dealing with repeatability and uncertainties of the enthalpy characterization are generally very scant and not encountered very often or only with qualitative assessments. This is a clear caveat, especially when considering any system design.

The determination of both the thermal and thermodynamical properties of a composite material containing phase change material is done thanks to an inverse method, which combines experimental measurements and numerical computations. Given first an in-house experiment, which allows us to test samples at a macroscopic scale (i.e., close to the real conditions) and to set various types of thermal stresses, and secondly the simulation of the corresponding thermal behavior, relying on an accurate thermodynamical modeling and taking into account the real operating parameters (e.g., thermal contact resistances and non-symmetric heat fluxes on each side), it is possible to characterize the solid and liquid thermal conductivities and heat capacities, as well as the temperature range associated with a non-isothermal phase transition and the associated latent heat. The specificity of the present approach is to allow, in a single step, a characterization of all the involved thermo-physical parameters that are usually required in simulation tools (e.g., EnergyPlus…). Moreover, the hitherto studies dealing with repeatability and uncertainties of the enthalpy characterization are generally very scant and not encountered very often or only with qualitative assessments. This is a clear caveat, especially when considering any system design. Therefore, for the first time ever, the present paper pays a special attention to the repeatability of the identification method and studies the scedasticity of the results, that is to say the deviations of the determined enthalpy curves, not only from a qualitative point of view but also by proposing quantitative arguments. Finally, the results are very promising since the agreement between all trials is excellent, the maximum error for all parameters being lower than 4%.

L’analyse bibliographique sur la modélisation de la trempe du verre fait apparaître plusieurs points clés de développement pour une utilisation dimensionnante et prédictive dans l’industrie verrière des arts de la table :
- Prise en compte et analyse détaillée des effets tridimensionnels. Les productions dans l’industrie des arts de la table sont très fortement tridimensionnelles, tant en géométries qu’en répartitions d’épaisseurs. L’évolution des designs va dans le sens d’une accentuation de ce point.
- Couplage conducto-convectif. Les conditions limites prises en compte dans la bibliographie portent quasi-exclusivement sur des coefficients de transfert imposés uniformément en surface. Les systèmes de refroidissement sont loin de produire réellement ce type de condition limite thermique.
- Optimisation. Au-delà du dimensionnement et des enjeux de production rappelés précédemment, la modélisation permet de mettre en place des boucles de calculs afin d’optimiser une fonction objectif donnée.
- Validations et vérifications expérimentales des contraintes produites. Les mesures de contraintes dans les verres trempés, notamment en configurations fortement tridimensionnelles représentent également un enjeu important notamment pour disposer d’outil de vérification et validation des modèles.},

Les articles en verre trempés représentent une part très significative en volumes de production et de vente sur les marchés liés aux arts de la table, pour lesquels ARC est un des leaders mondiaux. En termes de production, l’exigence accrue des cahiers des charges clients, de qualité de production, mais aussi de limitation de l’impact environnemental, nécessite une maîtrise accrue et des connaissances plus fines et précises du process. Ainsi, une attention très particulière est portée par ARC à cette phase particulière du procédé verrier et une constante innovation est apportée pour améliorer ses performances.
En parallèle d’études et de recherches menées sur bancs expérimentaux spécifiques et de tests sur chaînes de production, la modélisation numérique représente un outil central d’investigation et de recherche.
La trempe du verre fait intervenir un nombre significatif de paramètres physiques et physico-chimiques tels que notamment les configurations géométriques, la thermique de refroidissement et de chauffage, ou encore la composition du verre.
L’analyse bibliographique sur la modélisation de la trempe du verre fait apparaître plusieurs points clés de développement pour une utilisation dimensionnante et prédictive dans l’industrie verrière des arts de la table :
- Prise en compte et analyse détaillée des effets tridimensionnels. Les productions dans l’industrie des arts de la table sont très fortement tridimensionnelles, tant en géométries qu’en répartitions d’épaisseurs. L’évolution des designs va dans le sens d’une accentuation de ce point.
- Couplage conducto-convectif. Les conditions limites prises en compte dans la bibliographie portent quasi-exclusivement sur des coefficients de transfert imposés uniformément en surface. Les systèmes de refroidissement sont loin de produire réellement ce type de condition limite thermique.
- Optimisation. Au-delà du dimensionnement et des enjeux de production rappelés précédemment, la modélisation permet de mettre en place des boucles de calculs afin d’optimiser une fonction objectif donnée.
- Validations et vérifications expérimentales des contraintes produites. Les mesures de contraintes dans les verres trempés, notamment en configurations fortement tridimensionnelles représentent également un enjeu important notamment pour disposer d’outil de vérification et validation des modèles. |

abstract = {This study is the first stage of a larger multidisciplinary research program about the environmental performances and functions of green walls in urban ecosystems. It aims to determine how green-walls contribute to the thermal insulation of buildings by measuring the thermal conductivities of green-walls’ components in controlled conditions. The study focused on complex green-wall systems, i.e. with a structure containing substrate in opposition with green-walls based on climbing plants. The four substrates were materials found in commercial substrate combinations. To compare, the thermal conductivities on two plants are carried out. In dry conditions, they showed conductivities of 0.062 W/m °C for sphagnum moss (Sphagnum cristatum), 0.060W/m °C for outdoor planting mix, and 0.105 W/m °C for clay balls and 0.051 W/m °C for substrate from a green-wall.

This study is the first stage of a larger multidisciplinary research program about the environmental performances and functions of green walls in urban ecosystems. It aims to determine how green-walls contribute to the thermal insulation of buildings by measuring the thermal conductivities of green-walls’ components in controlled conditions. The study focused on complex green-wall systems, i.e. with a structure containing substrate in opposition with green-walls based on climbing plants. The four substrates were materials found in commercial substrate combinations. To compare, the thermal conductivities on two plants are carried out. In dry conditions, they showed conductivities of 0.062 W/m °C for sphagnum moss (Sphagnum cristatum), 0.060W/m °C for outdoor planting mix, and 0.105 W/m °C for clay balls and 0.051 W/m °C for substrate from a green-wall. Vegetation conductivities were also measured for ivy (Hedera helix) and Virginia creeper (Parthenocissus quinquefolia). As expected, conductivities were quite high (between 0.220 and 0.274 W/m °C).
