在非结构化网格CFD求解器中采用共轭传热模拟方法对冷却涡轮机叶片Mark II和C3 X的热负荷进行了预测。在该模拟中，流体域和固体域同时求解，以满足流体和固体边界上热流和温度的连续性。此外，还应用了-I -Re-10转捩模型来预测涡轮机叶片绕流中经常发生的、严重影响材料热负荷的边界层转捩。二维和三维计算的预测热负荷结果与获取叶片吸力侧过渡的测量数据非常一致。
Conjugate heat transfer simulation method was implemented in the unstructured-mesh CFD solver to predict the thermal loads of cooled turbine vanes, Mark II and C3X. In this simulation, the fluid domain and solid domain are solved simultaneously satisfying the continuity of the heat flux and temperature on the boundary of the fluid and solid. In addition, �I -Re�﷿ transition model is applied to predict the boundary layer transition which often occurs in the flow around turbine blades and affects the material thermal load seriously. The predicted thermal load results from the two- and three-dimensional computations are in close agreement with the measurement data capturing the transition on the suction side of the vanes.
