摘要

通过传热试验法对不同缝槽进气孔间距的纯气膜冷却效率进行研究。研究所用气膜缝槽结构无收缩

进气孔与舌片垂直。试验中主流湍流强度在10%以上

测量气膜绝热壁温以确定其重要冷却效率描述参数——绝热温比。试验结果表明:缝槽进气孔间距对气膜冷却效率影响很大

减小进气孔间距

可以减小缝槽几何特征参数MIXN

明显提高气膜的绝热温比。

Abstract

The film-cooling adiabatic effectiveness was investigated by the heat-transfer experimental method with different pitch between inlet holes of the slot film.The adiabatic wall temperature was measured to calculate the important parameter for film-cooling effectiveness

defined as adiabatic effectiveness.The slot film configurations featured no convergence and inlet holes perpendicular to slot lip.The main stream turbulent level was higher than 10% in all experiments.The experimental results indicate that the pitch between inlet holes plays important role in film-cooling effectiveness.The adiabatic film-cooling effectiveness increases with the decrease of the pitch between the inlet holes and the slot geometric parameter MIXN.
