叶片冷却;
The development of hollow blades with high efficient cooling have high requirements for the preparation and properties of the ceramic core.
高效冷却空心叶片的发展对陶瓷型芯的制备技术与性能提出了更高要求。
But, with increasing blowing rate from 0.8 to 1.5, the influence of the stationary vanes 'unsteady wakes on the moving blades' cooling effectiveness is reduced.
另外,吹风比从0.8增大到1.5时,静叶非定常尾迹对动叶气膜冷却效果的影响降低。
