动叶局部弯曲对压气机流场和性能的影响
Influence of Partially Bowed Rotor Blades on the Flow Field and Performance in a Compressor
摘要
Abstract
To analyze the influence of partially bowed blades on the compressor’s flow field and performance,a transonic rotor, NASA Rotor67,is selected as the baseline.Numerical results show that both positive and negative bowed rotor blades could help improve compressor performance in different operation points,and the positive bow has a better effect relatively.In the near peak efficiency point,the positive bow increases the compressor efficiency,while negative bow could shrink flow separation areas and improve the flow field.关键词
