气固两相平面叶栅气动特性的试验研究

EXPERIMENTAL INVESTIGATION ON GAS-PARTICLE FLOW IN CASCADES

一、前言 Tabakoff等人对气固两相平面叶栅叶片表面上气相压力进行了测量,但是没有对栅后气流参数进行测量。 本文在特殊的气固两相流风洞中,测量了单相纯气流和气固两相流分别以冲角i=-10°、0°、10°流过平面叶栅时,叶片表面上气流压力和栅后气流参数,其目的在于分析冲角对气固两相平面叶栅气动特性的影响。

Detailed measurements are made for three inlet attack angles, i= -10°, 0°, and 10°, and for two mass concentrations, α = 0 and 0.07%. Results show that, with an increase in attack angle i, the pressure distribution on the pressure side rises, outlet flow angle decreases, and wake deviation appears.
