The purpose of this paper is to perform a computer simulation of the pressure field generated by a marine propeller. The data generated from the simulation could later be used to study the vibration response of the ship. The study of the pressure fluctuations induced by the propeller requires the analysis and modeling of very complicated flows. Typically Computer simulations are checked against experimental data to verify the accuracy of the model. As an alternative a simpler model based on computational fluid dynamics will be constructed and verified against published studies to gain some insight into the accuracy of the computational fluid dynamics analysis. A study performed by John Breslin (1964) at Massachusetts Institute of Technology will be used as a benchmark to determine the validity of using computational fluid dynamics as a model to predict pressure fluctuations from a marine propeller. The experiment replicates the type of pressure fluctuations that the hull of a ship would see in normal operation. The geometry is simple which will allow it to be modeled easily. The results will provide information regarding the accuracy of using the simulated pressure fluctuations to predict the actual propeller pressure field.
