摘要

为了研究转捩对气热耦合计算的影响

在B-L代数模型与SST(shear stress transport)k-ω二方程模型的基础上

增加了两类基于间歇因子的转捩模型:代数AGS(Abu-Gharmam Shaw)模型与一方程间歇因子输运方程.选取NASA-MARKⅡ跨声速叶片为算例

分别采用全湍流模型与加入转捩的模型进行气热耦合计算.数值计算结果与试验对比表明由于能够预测附面层中的转捩过程

采用转捩模型的耦合计算得到的结果与试验吻合最好

由于在叶片壁面附近的网格较粗

采用间歇因子输运方程的转捩模型计算的结果要逊于采用代数转捩模型的结果.

Abstract

The Abu-Gharmam Shaw(AGS) transition model and a one-equation intermittency transition model were added into the Navier-Stokes(N-S) solver

HIT-3D

so as to investigate the effect of laminar-turbulent transition on predicting thermal load of vane.The test case was 5411 run of NASA-MARKⅡvane

a transonic turbine vane.The full turbulent models and transition models were employed by the coupled heat transfer simulations.The results show that the transition model can predict the transition process in the boundary layer near the vane

and that the simulations with such models lead to thermal load matching well the experiments.Since the grids cells near the vane surface are coarse

the simulations with the intermittency equation lead to results worse than those with the algebraic transition model.
