Abstract

In this study, the Reynolds-averaged Navier-Stokes(RANS) analysis were conducted to investigate the difference in the results of cavitation behavior around a hemispherical head-form body based on different cavitation models. An open-source software, OpenFOAM, was utilized for this purpose, and the Merkle, Kunz, Schnerr and Sauer models, as provided by OpenFOAM, were chosen as the cavitation models. To assess the influence of the cavitation models, we analyzed the cavitation shape around the cylinder, the time-averaged pressure and velocity, and the velocity fluctuations.
