某型三叶螺旋桨的气动特性数值模拟及试验

Aerodynamic numerical and test study of a three-blade propeller

以某型三叶螺旋桨为研究对象,基于RANS(Reynolds-averaged Naiver-Stokes)方程和SST(Shear Stress Transport)湍流模型的多重参考坐标系MRF(Multiple Reference Frames)方法对该三叶螺旋桨进行准定常数值模拟和性能计算。通过与试验结果对比,对三叶螺旋桨不同转速下的静态拉力、扭矩和效率进行了验证分析,得到拉力偏差值在2%左右,扭矩偏差值在10%左右。经过比较发现,计算结果与试验结果吻合良好,可为通航飞机螺旋桨的模拟和设计提供参考。

Propeller slipstream and performance of a three-blade propeller were simulated using Multiple Reference Frames （MRF） quasi-steady method based on the Reynolds-averaged Naiver-Stokes （ RANS ） e- quation and Shear Stress Transport （SST） turbulence model. Thrust, torque and efficiency of the three-blade propellers caused by simulation were analyzed under different rotational speed compared to the results of tests. Deviation value of the tension is around 2%, and deviation value of the torque is about 10%. It is found by comparison that calculation results are in good agreement with those obtained from the test results, which can provide the guidance for propeller design applications.
