Application of a Potential Flow Code (PROPCAV) for Surface Piercing Propeller Analysis

Abstract

A medium-fidelity analysis method for quickly evaluating blade loads for surface piercing propellers with a potential flow unsteady propeller force panel code, PROPCAV, has been evaluated and shown to be viable. Two case studies were examined, consisting of 14.7 in (0.373 m) diameter Mercury Marine Revolution 4 propellers of two different pitches: 21 in (0.533 m) and 23 in (0.584 m) pitches. The results from PROPCAV for maximum and minimum thrust predictions were compared to high-fidelity unsteady Reynolds-averaged Navier-Stokes (U-RANS) computational fluid dynamics (CFD) simulation results and agreed well (within 6.6 percent).
