级效率(涡轮机)

The ejected coolant interacts with the external flow near the endwall and generates aerodynamic and thermodynamic losses in the process . this reduces turbine stage efficiency and together with the consumption of cooling air is detrimental to the overall cycle efficiency
但这种方法中喷射的冷空气与端壁附近的外流场相互作用产生气动力和热动力损失，并且消耗冷却空气，从而损害涡轮的整体循环效率。
