本文是以数千个实验数据为基础,定量地给出了在前后排孔流量不等时,在整个凹面和凸面上的气膜冷却有效温比分布的全貌,使人们清楚地看出在不同条件下不同曲面上的特征。为设计者提供了有实际价值的依据。同时还对射流中的二次流的现象与规律进行了探索性的分析,值得进一步探索和研究。 Based on thousands of experimental data, this paper gives a quantitative overview of the distribution of effective temperature and temperature distribution of the film cooling over the entire concave and convex surfaces with different flow rates of front and rear row holes, Conditions on different surfaces of the features. For designers to provide a basis for the actual value. At the same time, the phenomenon and regularity of the secondary flow in the jet are also explored, and it is worth further exploration and research.
