摘要
以某型电动飞机螺旋桨为研究对象,基于RANS方程和SST湍流模型的MRF方法对螺旋桨进行高精度滑流准定常数值模拟和性能计算。为了验证计算和设计的合理性,对该型螺旋桨进行了缩比模型风洞试验。试验结果表明,数值模拟计算结果与风洞试验数据吻合较好,证明该方法可为螺旋桨设计提供指导。
An electric powered aircraft propeller was studied. Propeller slipstream is simulated using the MRF quasi-steady method based on the RANS equation and SST turbulence model. In order to prove the reasonability of the design and calculation, the scaled model wind tunnel test has been made to appraise it. The results indicate that there is a good agreement between simulation results and wind tunnel test da- ta, indicating that the simulation method could provide a guidance for propeller design.
