介绍了γ-Reθ转捩模型,补充了相应的关联函数。基于平板的试验数据在中国空气动力研究与发展中心(CARDC)的trip软件平台上对该关联函数进行了标定,并研究了关联函数的变化对转捩结果的影响规律。通过修正与SST湍流模型的结合,改进了转捩位置后壁面摩擦阻力系数偏低的状况。 Introduced the γ-Reθ transition model, supplemented the corresponding correlation function. The correlation function was calibrated on the trip software platform of China Aerodynamic Research and Development Center (CARDC) based on the plate test data. The influence of the change of the correlation function on the transfer result was also studied. By modifying the combination with the SST turbulence model, the condition that the coefficient of frictional resistance of the wall is low after the transition is improved.
