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.},

abstract = {Experimental measurements, steady (RANS) and unsteady (URANS) numerical simulations are performed on a 3.5:1 prolate spheroid at angles of attack from 0° to 90°. The Reynolds number considered is Re_L=2.57*10^6, corresponding to the wind tunnel conditions. CFD simulations are performed with OpenFOAM, using the k-omega SST and the Spalart-Allmaras turbulence models. Analyses of aerodynamic coefficients and surface pressure show a good agreement between CFD simulations and experimental results. The turbulent structures in the wake of the spheroid have a complex topology, strongly dependent on the angle of attack considered. Results of URANS simulations allow to identify turbulent structures that are steady and asymmetric at low angles of attack, symmetric and unsteady at higher values. The configuration at AoA=90° is the most complex with the presence of disorganized and unstable structures.},

abstract = {Dust emissions due to aeolian erosion of exposed granular materials are strongly influenced by grain size distribution. Non-erodible particles that are too heavy to be lifted into the air play a protective role in the aeolian erosion process attenuating emission, which is known as the pavement phenomenon. To date, there is no approach that reliably predicts the reduction in emissions caused by their presence on an aggregate surface. In this work, an analytical model was developed to quantify emissions from particle beds with a wide size distribution. As non-erodible particles accumulate, changes in surface characteristics create increasing shelter for the erodible portion of the bed until the shear on the erodible surface reaches a minimum and emissions cease. The proposed emission model describes the relationship between this minimum value of wind shear and the eroded depth of the bed after the pavement, which in turn gives the emitted mass. In addition, wind tunnel experiments were carried out in order to broaden knowledge of the pavement phenomenon and validate the modelling. A bimodal particle size distribution of sand with erodible and non-erodible particles was used for the tested velocities. Three experimental measurements were carried out: (i) continuous weighing of the emitted mass, (ii) eroded depth of the bed at regular time intervals and (iii) final cover rates of the non-erodible particles using digital analysis of sand bed pictures after experiments. Good agreement between the modelling and experimental results was found. The emission model proposed herein is a simple algebraic expression that demands low computational effort. This approach may serve as a base for an emission model for application in granular materials stockpiles.},

abstract = {The aim of this paper is to propose an efficient method to evaluate the Added Masses of generic shape bodies in infinite fluid or in the proximity of external walls. The Added Masses (AM) are the result of the inertial reaction of the fluid in response to an accelerated movement of a body immersed in it. The AM effects are more evident when the body density is similar to that of the surrounding fluid, as in the case of airships. In the take-off or landing phases, the proximity to the ground causes an increase in the Added Masses that must be correctly estimated to properly size the airship controls. In our method, the calculation of the Added Masses matrix is carried out by the Boundary Element Method (BEM). To verify the accuracy of the results, the study cases are based on simple shapes, whose Added Masses are well known. The analyses in infinite fluid and in the presence of a flat wall are carried out. Numerical results are compared to the theoretical values found in literature. The calculated Added Masses are intrinsically dependent on the mesh definition and the relative error, referred to the theoretical values, depends on the surface and volume discretization. In the case of interaction between geometries with complex shapes, the influence on the Added Masses is very difficult to predict without a numerical approach. The method proposed gives a good compromise in terms of quality of results and computational cost.},

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.},
