Summary:

This paper contains a brief description of the numericalapproach used to simulate the flow of cavitating liquids that wasimplemented in FloEFD software. Some computational resultsobtained using this approach are presented. The calculations used3D Navier-Stokes equations coupled with the k-e turbulence modeland equilibrium cavitation model.It is assumed that this process occurs at a fixed temperature(so-called isothermal cavitation). The validity of this assumptionis confirmed by numerous test data. Since the liquids heat capacityis large enough to neglect the heat generated in the phasetransition, it practically doesn't change the liquidstemperature. This approach allows a minimized number of requiredthermodynamic properties of the liquid. A new cavitationcalculation method of a 2-phase-2-solver (Hybrid density- andpressure-based splitting scheme) calculation is introduced thatapplies appropriate Computational Fluid Dynamics (CFD) solvers tothe low and high compressible region and therefore creating ahybrid solver splitting scheme.Application examples for different industrial liquids are shownwith flow in injectors, pumps and around hydro foils and presentthe validation of the model compared to theory and experiment. Thecomparison of the calculation results against test data shows asatisfying agreement of the model
