某重型燃机一级动叶空气流量特性研究

Research on Air Flow Characteristics of a Heavy Gas Turbine 1^(st) Blade

对某重型燃机透平第一级动叶进行了冷态三维数值模拟及试验研究,分析了不同的压差下该叶片的内部空气流量特性,得到了叶片内部空气流量的分配比例。研究工作为工程化叶片冷却结构流量特性检测提供了依据。

This paper implemented cooling state 3-d numerical simulation analysis and air flow characteristic test research on a heavy gas turbine 1 st blade. Analyzed the internal air flow characteristic of this blade under different pressure differentials and got the blade internal air flow rate distribution proportion. The research works provide the basis for engineering test of the blade cooling configuration air flow characteristic.
