TWO-WAY COUPLED REYNOLDS AND RAYLEIGH-PLESSET EQUATIONS FOR A MULTIPHYSICS FULLY TRANSIENT CAVITATION MODEL
The present paper discusses and differentiates between the sources of vaporous, gaseous and pseudocavitation and offers a physics-based approach that solves the coupled Reynolds (RE) and Rayleigh-Plesset (RP) equations in a fully transient environment. The RP solution calculates a time dependent void fraction synchronized with the RE transient solution, where density and viscosity are (re)calculated at every grid point of this homogeneous two-phase fluid. The growth and expanse of the cavitation zone is physics-based and thus can accommodate evaporation, diffusion, or pseudo-cavitation as separate processes.
