Other frequent problems occurring are vibration and noise because of the cavitation induced pressure fluctuation on the hull. This paper aims to review the cavitation phenomenon on ship propellers, which have been performed in the previous research. Several techniques to obtain reliable observation and prediction of cavitation inception, related to the adverse effect on material damages are discussed through advance experimental laboratory and numerical modeling. Then, prediction and observation of cavitation behavior on the full scale and model scale, cavitation flow behind hull conditions, and geometry modification of the skew propeller are thoroughly discussed. © 2020 The Authors.

1. Introduction Cavitation is a phenomenon of fluid mechanics that can widely found on every machine which operated in the fluids, especially in turbomachinery. This phenomenon also exists in various marine applications (Yusvika et al., 2020). Ship propeller is a component of the ship propulsion system that has an interaction directly with water. When
