segregated is correct?
Hallo CFD engineers,
I am solvig the centrifugal compressor(impeller-diffuser interaction)preoblem. This is an unsteady,average Mach nunmber Ma=0.7, ideal gas, sliding mesh problem... I know that recomended is coupled solver. But when I use a coupled solver I have problem to get convergenced solution. On the other when I use a segregated solver the problem disapears. Residuals decrease about 3 orders of magnitude, lift coeff estimates sinusoidal characteristic, mass imballance is less than 2 percent.
Is it allowed to use the segregated solver in such compressible case? What to think about the results? Need Your advice.
