Modèles aux tensions de Reynolds avec prise en compte de l'intermittence de frontière

Abstract : The goal of this PhD thesis is to optimise a Reynolds stress model. Some constraints are applied to the length scale transport equation in order to take into account the effect of a pressure gradient on the structure of the boundary layer. This leads us to revisit the analysis of the behaviour of turbulence models at the vicinity of a free stream edge. The behaviour is different from what has been assumed before as the expected power law solution is contained in a more complex solution. This study proved that the constraints for the free stream edge are incompatible with the other constraints. The intermittent character of the free stream edge is taken into account in order to unlink the behaviour of the model at the free stream edge from its behaviour in fully turbulent regions. The model deduced from this analysis fulfils all the constraints and is calibrated on free shear flows and boundary layers where the constraints significantly improve the quality of results.
