| 摘 要： | 本文采用三维定常数值方法计算了某气膜冷却涡轮导向叶片流场。叶片的气膜冷却流动运用了源项模拟方法。将每排气膜孔用槽缝代替。计算的导叶能量损失系数和出口气流角与试验数据吻合良好。

| Abstract: | In this paper steady three-dimenslonat numerical calculation was performed in order to investigate the effects of film cooling on turbine stator flow fields. A row of cooling holes was modeled as a slot. Using source terms simulated film cooling flow in the stator. The effects of film cooling on the aerodynamic loss in terms of energy loss coefficient and the outlet flow angle were analyzed. The simulation results were agreed well with the experimental results, |
