Une methode d'elements finis pour le calcul des ecoulements compressibles utilisant les variables conservatives et Ia methode SUPG
Keywords:
Navier-Stokes and Euler equations, conservation variables, SUPG, shock capturing, engine intakeAbstract
The Navier-Stokes and Euler equations are solved in a conservative form and using the conservation variables. The variational formulation and the corresponding finite element approximations are discussed. For high speed flows, the numerical model has to be stabilized. We used a SUPG method along with a shock capturing operator. The stabilization techniques and the solution algorithm are described. Some numerical tests are carried out to validate the code. This model is employed to simulate the flow in an engine intake.
