Abstract

This effort explores the complex phenomena of cavitation inside different liquid geometry interacting with a planar shock wave by employing the use of Computational Fluids Dynamics (CFD) modeling. The simulation is an unsteady multiphase simulation utilizing a finite volume commercial code known as STAR-CCM+ . Two primary cavitation models were employed: the Schnerr- Sauer model and the Full Rayleigh-Plesset model. The initial investigation involves validating the numerical simulations against available experimental data. Subsequently, a comprehensive parameter study was conducted, examining the effects of varying Mach numbers, liquid geometries, and seed densities on the cavitation phenomenon. Results indicated that cavitation occurs within the liquid geometry due to the low-pressure spike, leading to significant pressure oscillations inside the liquid geometry.
