Numerical Simulation of Hydrodynamic Performance for Cycloidal Propellers

The hydrodynamic performance is the key to the design of the cycloidal propeller. In the research, the numerical model is established and the hydrodynamic performances under different advance coefficients and pitch ratios are analyzed for a scaled model of cycloidal propeller, by means of computational fluid dynamics (CFD) method. The proposed simulation method is proved to be correct by comparing the numerical results of the hydrodynamic parameters with the data of the open water experiment. The result of the hydrodynamic performance research can provide effective supports for design and optimization of the blades and the propellers.
