本文综合评述了气膜冷却壁面换热系数有关文献的公式。对谢象春和Spalding的理论分析方法,分别通过计算同实验结果进行了比较。通过电加热气膜冷却平板的换热实验,建立了一组计算气膜冷却平板换热系数的准则公式。
In this paper, a comprehensive review of the literature film cooling wall heat transfer coefficient of the formula. The theoretical analysis methods of Xie Xunchun and Spalding are respectively compared with the experimental results by calculation. A set of criteria formula for calculating the heat transfer coefficient of film cooling plate was established by the experiment of electric heating film cooling plate.
