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。
The velocity coefficient and energy of gas-solid two-phase flow through the compressor cascade are studied by measuring and analyzing the pressure and velocity of the gas flow along the pitch and height distribution of the planar cascade of the gas-solid two-phase compressor The loss coefficient varies with particle concentration and angle of attack. The test was carried out at an angle of attack i = -10 °, an air velocity of 0 ° c = 10 m / s and particle mass concentrations α = 0%, 2.0% and 2.7%. The results show that the energy loss of the gas-solid two-phase flow through the compressor cascade is larger than that of the single-phase pure gas flow, and the difference between the two is greater as the particle concentration and angle of attack increase.
