Compressible flow computation with STAR
Dear STAR users, I have tried using STAR for typical compressor volute flow analysis. What we have is inlet with velocity components and pressure and mass flow rate. We tried running with pressure and direction cosine data at inlet and outlet with mass flow rate. But we are finding always issued with convergence with pressure type of BC with STAR. I am able to get solution with velocity components at inlet and slow split type BC at outlet and a reference pressure at inlet. I assume for compressible flow there should be atlast one pressure based BC I would appreciate your suggestions for this kind of problems.
