Numerical study on multiphase flows was performed to analyze the compressibility effects to the cavitation model dependency of model constants. The computation was performed within converging-diverging nozzle. Compressibility and incompressibility flows were compared in the present study to consider the compressibility effects in the two phase mixture. Two different cavitation models of Merkle et al. and Kunz et al. were used to simulate the evaporation and condensation processes. The governing equation was adapted the fully unsteady compressible preconditioned Reynolds-Averaged Navier-Stokes equations. The results indicate that the addition of compressibility effects on multi-phase flows could reduce the cavitation model’s dependency of model constants to get more significant physical accuracy, and Merkle"s cavitation model has higher numerical accuracy rather than Kunz’s cavitation model in compressible and incompressible systems.
