摘要/Abstract

摘要： 为了研究引气对压气机流场的影响,采用数值方法对压气机引气的简化数学物理模型进行了引气量、引气面积、引气结构角度及长度四个引气控制参数共49个方案的对比探究。结果表明:受到引气抽吸作用的影响,引气槽上游主流的流动加速,下游主流减速。引气参数对主流热力参数的影响呈规律性,引气量主要决定热力参数变化的程度,引气面积主要改变热力参数变化的范围,而引气结构的角度和长度则主要影响引气结构内部的流动形式。 

Abstract: In order to study the impact of bleeding on compressor performance, this paper sets up a simplified mathematical and physical model, and uses numerical simulation to explore parameters of bleeding rate, bleeding area, the angle and length of bleeding structure in 49cases. Studies show that due to the effects of the bleeding, the mainstream flow accelerates in the upstream of the bleeding groove, and decelerates in the downstream. There is a certain pattern in the impact of bleeding parameters on mainstream thermal performance. Bleeding rate mainly determines how much the thermodynamic parameters change, and bleeding area mainly affects where the thermodynamic parameters change,while the angle and length of the bleeding structure influence how the internal bleed air flows. 
