Abstract

This article is aimed to provide a comprehensive understanding about Computational Fluid Dynamics (CFD) analysis of a ship propeller and the validation of the results obtained in the analyses with those of open water tests. The open water tests of the propellers and their outputs are explained briefly. Alternative computational solutions and its importance are also emphasized. A propeller of the modified type of Wageningen B.4 was investigated to validate CFD results.It is also aimed to focus on cavitation phenomena of this propeller. Nature of cavitation is introduced and the aforesaid propeller is also investigated to visualize the starting and development phases of cavitation. The simulation results of both cavitating and non-cavitating flows are compared with the experimental data.
