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.%An introduction is given of γ-Reθ transition model, and the experimental correlation which has not been published by Menter is supplemented in this paper.In the trip software of China Aerodynamic Research and Develop Center (CARDC) the experimental correlation is demarcated base on the experiment data of flat.Some conclusions about the effect experimental correlations on transition position are obtained.The modified binding mode with SST turbulent model improve deflection of friction drag force coefficient.
