    Abstract

    This paper presents a hydrodynamic analysis of a CLT propeller using a lifting surface vortex lattice method. The UPCA91 lifting surface code has been extended for this purpose to account for the effect of endplates. The code is intended for the preliminary analysis of geometry variations from the standpoint of pressure pulses at frequencies which are multiples of the propeller blade passage frequency. The paper shows the unsteady analysis of a passenger ship propeller. A comparison of differences between computed and measured pressure pulses obtained for a cavitating condition is provided.
