| 摘 要： | 通过对气固两相压气机平面叶栅后,沿栅距和叶高分布的气流压力和速度的测量与分析,研究了气固两相流流经压气机平面叶栅时的速度系数和能量损失系数随粒子浓度和攻角改变而变化的规律。试验是在攻角i=-10°、0°气流速度c=10m/s及粒子质量浓度α=0％、2.0％和2.7％的工况下进行的。结果表明:气固两相流流经压气机平面叶栅时能量损失比单相纯气流的大;而且随着粒子浓度和攻角增大,两者的差别也愈大。

| Abstract: | The energy loss of gas-particle two phase flow in a nozzle cascade has been investigated experimentally. Detailed measurements are made for three mass concentrations, α = 0, 2.0%, 2.7% and for two inlet angles of attack of i=-10 ° . 0 ° , and for an inlet velocity of C= 10m/ s. The results indicate that the solid phase has certain effect on the energy loss of gas phase. With an increased mass concentration and inlet angle of attack, the energy loss of gas-particle two phase flow in a nozzle cascade will increase. |
