【Abstract】 This paper predicts the hydrodynamic performance of propeller by high-order surface panel method. Using the B-spline method to express the surface of blade、hub and velocity potential distribution of propeller. The trailing vortex surface is represented by a number of small hyperboloidal quadri-lateral panels with a constant doublet distribution. The non-linear Kutta condition of equal pressure on upper and lower of the trailing edge is executed by the iterative procedure.The calculated results for open-water characteristics of propeller and pressure distribution on the blade are in satisfactory agreement with experimental data.更多还原
