UDS for compressible flow
Hi, Quick question on Upwind differencing scheme in finite volume, for compressible flows, where density and velocity both vary.
I know that when density and velocity are constants, then you would have:
if
and
if
Can someone please tell me what happens when density and velocity are variables. Would I get something like this?
if
if
I'm guessing the same principle applies even if density is constant and velocity varies.
I didn't manage to find anything useful online. Please help!
Thanks!
