| 摘 要： | 本文采用CFD软件CFX—TASCflow对带冷气影响的某高压涡轮级流场进行了数值模拟。叶片的气膜冷却流动运用了源项模拟方法，将各排气膜孔用槽缝代替。计算中还考虑了动叶叶尖间隙的影响。

| Abstract: | A steady of three-dimension numerical simulation was conducted on high pressure (HP) turbine stage by using CFD software CFX-TASCflow with SST turbulen ce. A row of holes is modeled as a slot. Film cooling flows have been simulated using source terms. Computation also takes account of the effect of tip clearanc e. |
