为了初步研究γ-Reθ转捩模型在高超声速领域的适用性,在自行开发的CFD程序中添加了该模型,利用T3系列平板算例对该模型的实现进行了验证;针对高超声速流动,选取压缩面绕流和双圆锥扰流等算例,分别利用该转捩模型、全层流模拟、以及传统的湍流模型进行了数值模拟计算,并与实验结果进行对比。计算结果表明,尽管该转捩模型是在低速流动的基础上发展的,它仍能准确预测高超声速流动下的转捩现象。 In order to study the applicability of the γ-Reθ transition model in the hypersonic field, the model was added to the CFD program developed by ourselves and the implementation of the model was verified by using the T3 series flat panel example. For hypersonic flow, Compressional surface flow and double-cone flow disturbance are calculated by numerical simulation using the transition model, full-layer flow simulation and traditional turbulence model, respectively, and compared with the experimental results. The results show that although the transition model developed on the basis of low-velocity flow, it can still accurately predict the transition under hypersonic flow.
