Default Entropy condition
Posts: n/a

I have a general question about the entropy condition. I heard, that the central differencing schemes violates the entropy condition, but the upwind does not. Is this true, for all kind of flows, or just for compressible flow? So far I actually thought, that I should use central differencing for my incompressible flows, whenever it does not oscillate (fine enough mesh)!? Is there any engineering cfd book, where I find some more explanation? Would be nice, if you have some hints...

Thanks! Flo
