摘　　要：本文使用数值模拟的方法对3种不同的风洞收缩段在压气机试验器进气系统中的流场特性进行了研究,以验证不同收缩段在试验器进气系统中的性能指标。数值模拟结果表明,3种模型出口截面流场的总压不均匀度、速度不均匀度和平均气流角均满足压气机试验要求,但是维氏曲线的模型在试验器进口静压测量截面的不均匀度更佳。In this paper the intake system of some compressor test rigis with three contraction sections studied using numerical simulation,to validate if flow quality meets the test requirements.The results show that,the total pressure uniformity,the velocilyuniformity and the average flow angle on the exit of three model can meet the test requirements,but the static pressure uniformity on the measurement capture of witozinsky contraction section model is better than others.
