Comparaison de solveurs numériques pour simuler la turbulence compressible

We focus on the computation of the hyperbolic system describing a turbulent flow for isentropic gas. An exact Riemann solver is computed, we construct the solution of the Riemann problem and thus we derive a Godunov scheme. We provide some numerical simulations to exhibit a comparison between Godunov scheme and two approximate solvers: Vfroe and Rusanov scheme.© 2000 Academie des sciences/Editions scientifiques et medicales Elsevier SAS
