A COLLOCATED FINITE VOLUME SCHEME WITH AN INTEGRAL FORMULATION FOR FLOWS WITH FLUID SECTION JUMPS

Résumé

We focus here on an integral approach to compute compressible or incompressible fluid flows in physical congested domains with discontinuous fluid sections. This approach is based on a multidimensional integral formulation of the fluid model equations and aims at unifying the porous approach used at component scale and CFD used at local scale. Its discretization uses a semi-implicit collocated finite volume scheme with an incremental pressure-correction algorithm, implemented in the open-source CFD software Code Saturne, version 6.0. Numerical tests are completed by simulating a plane steady-channel flow with a fluid section jump. The results are compared to the analytical solution and the computation obtained with a standard equivalent porous model.
