The advanced small gasturbines feature small mass flow ratio, short vanes and blades with low aspect, high second flow and blade tipleakage losses, and low efficiency.
先进的小发动机涡轮的流量小,叶片短,展弦比低,二次损失及叶尖漏泄损失大,效率低,温度高冷效差。
2
Downstream rotor-stator interaction increases the unsteady fluctuating intensities of the rotor tip clearance flow and the tipleakage loss.
下游静叶干涉增加了动叶顶部间隙流的非定常波动强度和泄漏损失。
3
The wake is mixing with the last rotor tipleakage vortex in the stator passage, leading to more substantial fluctuations in the flow field.
