桨叶根部负荷及毂涡能量利用研究一直是螺旋桨设计研究工作的重要内容之一。本文采用RANS方法进行敞水螺旋桨定常数值模拟,并与LDV流场测量数据对比验证了数值模拟的可靠性。进一步分析了3个不同环量分布形式螺旋桨的毂涡结构差异,阐述了螺旋桨根部负荷对毂涡结构的重要影响。
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.
