摘      要：The paper addresses the Large-Eddy Simulation(LES)of the turbulent wake of the Ahmed car *** this end we use a Fourier-Chebyshev multi-domain solver and the LES capability is implemented through the use of the Spectral Vanishing Viscosity(SVV)method,completed with a near-wall correction.A“pseudo-penalizationtechnique is used to model the bluff *** of the present SVV-LES results with the experiments and also with a more classical Finite Volume LES are provided.
