A calculation method for pressure fluctuation on a finite flat plate above a propeller with cavitation is introduced. First, the fundamental equations and numerical procedures about pressure fluctuation on a finite flat plate above a propeller without cavitation are described and the calculation results are compared with experimental data. Next, a calculation method for a steadily cavitating propeller is described. This method is based on the simplified surface panel method "SQCM". SQCM has already been applied to steady and unsteady 2-D and 3-D cavitating wings and showed a good agreement with experimental data. In the present study, SQCM is extended to calculate the performance of a steadily cavitating propeller and the calculation results are compared with experimental results. Finally, a calculation method for pressure fluctuation on a finite flat plate above a steadily cavitating propeller is described and the calculation results are compared with experimental results. Through these applications, the capability of the present method is examined.
