叶根端壁换热特性实验研究

EXPERIMENATL STUDY OF ENDWXLL HEAT TRANSFER IN TURBINE CASCADE

本文采用流动显示及传质模拟传热的实验方法研究了平面叶栅通道中的端壁流动及换热特点，结果表明攻角和Ｒｅ数对端壁流动及局部换热有影响，绘制了等Ｓｔ数曲线分布图，在本文中流动显示结果和传质模拟传热实验结果是符合的。

This paper discusses the flow and heat transfer of the endwall in a planar turbine cascade. The results give out the influence of the incidences and the Re numbers on the endwall flowing and the local heat transfer coefficency, give out the graphies of the equal St number for different incidences and Re numbers. In this paper, the results of flow visualization are same as the results of the mass transfer imitateing heat transfer.
