摘要/Abstract

摘要： 双轴压气机实验台径向进气系统尺寸限制多、涵盖流量范围广，供气品质难以保证。传统的导流筋板方案适用流量范围窄，不能满足要求。提出一种新颖的设计方案，充分运用蜂窝整流器均流和导向的特点来改善气流品质。模拟结果表明，在全流量范围内该进气系统出口截面最大气流角小于1°，速度不均度小于4.07%，总压恢复系数大于97.3%。完成的部分实验结果也表明气流品质较好。

Abstract: Considering the geometry restraints and wide mass flow range requirements， the discharge quality of the radial air intake system for a dual shaft compressor test rig is difficult to be guaranteed. Traditional solution like multiple guided vanes could not meet the requirements over wide mass flow range. A novel design was explored to improve flow uniformity， which made full use of the uniforming and guiding characteristics of honeycombs. The numerical results show satisfactory discharge distributions at the exit of the system over wide mass flow range， the maximum flow angle is less than 1°， the nonuniformity of velocity is less than 4.07%， and the total pressure recovery coefficient is higher than 97.3%. Furthermore， some experiment results show good flow qualities as predicted.

Key words: Intake system；Dual shaft compressor；Flow uniformity；Honeycombs
