The Influence of Propeller/Hull Interaction On Propeller Induced Cavitating Pressure

Sing-Kwan Lee, Hamn‐Ching Chen

Open publisher page 6 citations

Abstract

Cavitation tests have shown that propeller induced cavitating pressure is sensitive to the inflow in front of the propeller. It is well-known that this inflow is different from the nominal wake in bare hull condition. Due to the interactions among the nominal wake, propeller, and hull, the real flow to the propeller behaves differently and affects the propeller performance, blade cavity pattern, and fluctuating pressure generated. In this study, comparisons between Euler and RANS (Reynolds-Averaged Navier-Stokes) equation simulations are performed to find out their differences on the predictions of propeller blade cavitation and its induced hull pressure.
