The temperature distribution of the nozzleguidevanes are affected greatly by the flow and heat transfer of the internal cooling passages.
涡轮叶片内部冷却特性直接影响到叶片的壁面温度分布，必须对其展开详细的研究。

Calculations showed that: with the guidevanes, the high-pressure water would have tangential velocity after it went through the nozzle and form more obvious swirling jet.
