摘要
较详细地介绍了某多级压气机修改前后,利用叶型受感部测取各级转子出口总压、总温分布的试验方法和结果。试验结果证明该方法是可行的,得到的转子出口流场数据是可信的。叶型受感部较大限度地降低了插入式探针对转子出口流场的干扰,为研究多级压气机级间匹配关系探索了一种新的测量方法。
The experimental methods and results using the airfoil sensors to measure total pressure and total temperature distributions behind the rotors in a multistage axial-flow compressor were presented. The experimental results demonstrate that the experimental method is feasible, and the flow field data measured behind the rotor are believable. The airfoil sensors can decrease the influence of a plugged probe on the flow field behind the rotor. A measuring method for studying matching in stages of multistage compressor is investigated.
