An immersed boundary method is coupled to a turbulent wall model and Large Eddy Simulation, within the Lattice-Boltzmann framework. The method is able to handle arbitrarily moving objects immersed in a high Reynolds number flow and to accurately capture the shear layer and near wall effects. We perform a thorough numerical study which validates the...
A new compressible pressure-based Lattice Boltzmann Method is proposed to simulate humid air flows with phase change. The variable density and compressible effects are fully resolved, effectively lifting the Boussinesq approximation commonly used, e.g. for meteorological flows. Previous studies indicate that the Boussinesq assumption can lead to er...
The present work focuses on shape optimization using the lattice Boltzmann method applied to aerodynamic cases. The adjoint method is used to calculate the sensitivities of the drag force with respect to the shape of an object. The main advantage of the adjoint method is its cost, because it is independent from the number of optimization parameters...
Cette thèse a pour objectif le développement d’un solveur adjoint dans ProLB, le logiciel d’aérodynamique basé sur la méthode de Lattice-Boltzmann utilisé chez Renault. Ce solveur adjoint permet de calculer les sensibilités surfaciques des efforts aérodynamiques sur un obstacle, typiquement un véhicule, par rapport à la forme de celui-ci. L’objecti...
