film cooling effectiveness的相关资料
film cooling effectiveness的用法和样例
- The film-cooling adiabatic effectiveness was investigated by the heat-transfer experimental method with different pitch between inlet holes of the slot film.
摘要通过传热试验法对不同缝槽进气孔间距的纯气膜冷却效率进行研究。 - And the spanwise cooling effectiveness is improved significantly when the distance between the two small coolant jets is longer and the blowing ratio is higher.
在各吹风比条件下，气膜孔下游有射流小孔时，冷却效率都有一定的提高，并且射流小孔间距较大时对两气膜孔中心线之间的横向平均冷却效率改善较大，吹风比较大时，效果更明显。
