Modélisation des effets thermiques et aérauliques dans les stations de métro

Abstract : This work aims at the physical and the numerical modelling of air motion and heat transport phenomena in subway stations. The study is based on an approach described by the unsteady three-dimensional Euler's equations completed by source terms. These equations are discretized with a finite volume method and solved by a SIMPLE algorithm coupled with a scheme as proposed by Van Leer. The spatial discretization is made by a cartesian grid. In order to take the relative motions of the coaches inside the station into account, a sliding grid method is implemented. To validate the model, calculations are compared to measurements of the flow generated by mixed convection in a rectangular open duct equipped with an heated plate in its central part. The study ends by some applications of the numerical code in the case of a typical Parisian subway station.
