newposter Guest Posts: n/a	Hi evereybody, Has anybody a detailed finite volume discretization for the navier-stokes-equations in compressible flow and extended SIMPLE algorithm... especially I need help for discretizing the compressible pressure-correction euqation, I don't know wether I make mistake there... My compressible SIMPLE is working well for steady state cases in ranges from Ma from 0-3., but I get problems by unsteady state problems... have I to change anything in momentum equations for compressible flows (except including density and the 2/3 term for diffusive fluexes...). I am using static enthalpy equation... thank you very much
