对本文模型而言,与实度相比较,叶尖损失对五叶片风轮的影响要大于三叶片风轮。
Compared with the solidity, the influence of tip loss on five-blade is bigger than three-blade for this model.
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。
The advanced small gasturbines feature small mass flow ratio, short vanes and blades with low aspect, high second flow and blade tip leakage losses, and low efficiency.
最后提出一个重要的组合参数,反映了叶片尖部载荷和叶尖间隙的流向分布对叶尖泄漏掺混损失的综合影响。
Finally, an important combination parameter was put forward to reflect the overall influence of blade loading and tip clearance distribution on the tip leakage mixing loss.
