摘要
在粒子质量浓度ａ＝２．０％、２．７％，叶栅进口气流速度ｕｇ＝２２ｍ／ｓ和冲角ｉ＝１７°、２７°多种工况下，测量栅后沿栅距和对高方向分布的气流参数．通过与纯气流条件下试验结果比较，分析了叶栅进口粒子浓度和冲角变化对压气机平面对栅后气体流动参数的影响．
Measurements of outlet flow for gas-particle two-phase flows through a compressor cascade were made under the following conditions: gas-phase inlet velocity μg = 10m/s,attack angles i= 17° and 27°, and particle mass concentration a= 2. 0% and 2. 7 %. It is observed that the particle concentration and attack angle have great influence on the outlet flow aerodynamic characteristic parameters along the pitch and length of the cascade.
