6) profile loss
叶型损失
1.
The test results show that,for this static cascade,using the aft-loaded profile and curved blade can not only reduce the profile loss,but also weaken the secondary flow.
实验结果表明采用后部加载叶型和弯叶片设计可以有效地减少叶型损失和二次流损失;同时变冲角性能得到极大改善,在±10°冲角范围内总流动损失系数变化不超20%,可以肯定该叶片改型设计是成功的。
2.
With the aid of a large database of measured profile losses,including in-house results and recent cases from the open literature,the profile loss predictions of Kacker and Okapuu have been improved.
借助于内部试验和公开发表的大量的叶型损失试验数据,在Kacker和Okapuu的叶型损失预测模型的基础上,提出一种改进的损失预测模型。
3.
Further,the impact of boundary layer separation and wake vortices on profile loss were analyzed.
对边界层分离和尾迹涡产生叶型损失的原因进行了分析,结果表明:尾迹涡的扰动作用使得成核过程发生了变化,且改变了水滴数和湿度的分布。
