某型发动机的实际涡轮盘腔冷却结构被简化成外缘预旋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＊）对主盘局部换热及流阻特性的影响。实验发现，冷气雷诺数、旋转雷诺数的增大，使主盘局部换热系数在盘缘附近迅速增大，而在接近盘心时出现负值；阻力系数随旋转雷诺数的增大而减小，随冷气雷诺数的增大而增大。
The actual turbine disk cooling structure of a certain type of engine is simplified to a rotating cavity model with outer rim pre-spinning gas inlet. Experimental results show that the Reynolds number (Reω), cold air Reynolds number (Rez) Gr *) on the main plate local heat transfer and flow resistance characteristics. The experimental results show that the Reynolds number and the revolving Reynolds number increase, so that the local heat transfer coefficient of the main plate increases rapidly around the rim of the main plate, while it reaches a negative value near the plate center. The drag coefficient decreases with the increase of the rotational Reynolds number Small, with the air-conditioning Reynolds number increases.
