COMPARISON OF CAVITATION MODELS FOR THE PREDICTION OF CAVITATION AROUND A HYDROFOIL
Abstract
In this paper, four different cavitation models were compared for predicting cavitation around a hy-drofoil. A blocked structured mesh was created in ICEM CFD. Steady-state 2D simulations were per-formed in Ansys CFX. For all cases, the SST turbulence model with Reboud’s correction was used. For Zwart and Schnerr cavitation models, the recommended values were used for the empirical co-efficients. For the full cavitation model and Kunz cavitation model, values for the empirical coeffici-ents were determined as the recommended values did not provide satisfactory results. For the full cavitation model, the effect of non-condensable gases was neglected. For all the above-mentioned cavitation models, the pressure coefficient distribution was compared to experimental results from the literature.
