螺旋桨水动力性能的影响因素分析

In order to analyze the influence factors on the hydrodynamic performance of the propeller,used CFD software to make numerical simulation of open water propeller. prepared the value of the propeller point by FORTRAN,modeled the propeller geometry by preprocessor ICEM and refined the local grid.The numerical simulation method was used to take variable scale research on the main geometrical parameters which influent the performance of propeller.Analyze the impact of various parameters which include propeller area ratio, pitch ratio and skewed on the performance of the propeller.The calculation results show that the area ratio and pitch have an important influence on the thrust performance of propeller, while the influence of skewed is relatively small.
