This paper describes an extension of 3D time-marching compressible Navier-Stokes solver (Part 1) for an incompressible application through the pseudo-compressibility technique suggested by Chorin. Effect of tip clearances on the mixed-flow pump is investigated. Static pressure distribution and intricate internal flow pattern is reasonably well predicted. Fine-tuning of the pseudo-compressibility parameter and grid size is required for improve convergence and stability.
