Based on the projection principle of propeller and its geometric parameters, using three-dimensional modeling software CATIA to establish a three-dimensional numerical model of propeller. Then according to the principle of computational fluid dynamics (CFD), the use of fluid dynamics software FLUENT numerical model for analysis and calculation of propeller. Using RANS method and combining with the RSM turbulence model propellers, three dimensional viscous flow field computation domain of discrete using unstructured grid method, using the relative rotating coordinates method (MRF) to simulate the movement of the propeller, in order to calculate the propeller under different into the coefficient of the flow field characteristics, and compared the numerical calculation results and experimental results of the propeller to determine the applicability of the method. Finally to study the properties of blockage effect and the ordinary propeller open water performance and propeller under the blockage effect of open water performance comparison, draw a blockage effect on propeller open water performance impact.
