Résumé :
|
Treatment of convective and pressure fluxes in the Euler and Navier-Stokes equations using splitting formulas for convective velocity and pressure, with a view to incorporate them in sequential pressure-based methods, is investigated. Two schemes : CVS (controlled variation scheme) and AUSM ( advection upstream splitting method) are explored for their accuracy in resolving sharp gradients. In part 1, basic concepts and the derivation of the CVS, along with its comparison to AUSM scheme are presented.
