| Abstract: | The propeller radial circulation distribution and hub vortex energy recycling is one of the important subjects in propeller design.To research the influence on hub vortex structure,the RANS method was adopted to simulate the steady propeller wake,According to the comparisons of CFD simulation and the results of LDV measurement,the calculation results are reliable.From the analysis of three different radial circulation distribution propellers,the differences of vortex structure were declared,and the relationship of propeller root load and hub vortex structure was discussed. |
