| 摘 要： | 本文利用传质比拟传热的方法,研究离散孔气膜冷却在整个弯曲壁面上沿与主流垂直方向的冷却均匀性。比较了单、双排孔和前、后排孔流量不等时,在不同吹风比的条件下,在凸、凹表面上冷却均匀性的特征。

| Abstract: | The film-cooling uniformity of discrete holes in the direction normal to main stream is investigated by means of heat and mass analogy. At different blowing ratios, the features of the film-cooling uniformity for one row and two rows of discrete holes are compared. It is found that the film-cooling uniformity on the concave surface is better than that on the convex one. |
