某型发动机的涡轮盘腔冷却结构被简化成外缘轴向进气的旋转空腔模型，以实验方法研究了旋转雷诺数（Ｒｅω）、冷气雷诺数（Ｒｅｚ）、哥拉晓夫数（Ｇｒ＊）对主盘平均换热特性的影响。实验发现，主盘平均换热系数随冷气雷诺数的增大而增加，随旋转雷诺数的增加而下降，随哥拉晓夫数的增加而增加。根据实验结果给出了计算主盘表面平均对流换热系数的经验关系式。
The cooling structure of a turbine disc cavity of a certain type of engine is simplified into a rotating cavity model with axial inlet air at the outer edge. Experimental Rex, Rez, Gr *) On the average heat transfer characteristics of the main disk. The experimental results show that the average heat transfer coefficient increases with the Reynolds number of the cold air, decreases with the increase of the rotational Reynolds number, and increases with the increase of the Goldschmidt number. Based on the experimental results, an empirical relational formula for calculating the average convective heat transfer coefficient on the surface of the main plate is given.
