摘    要: <正> 1.试验设备及方法 试验用的弯道示于图1。弯道的横断面呈矩形50×40mm~2,平均半径R_c=75mm,R_c╱D=1.5,D是当量直径。无量纲半径γ~*=(γ—γ_o)/(γ_—γ_o),其中γ_i是弯道内侧壁半径,γ_o是外侧壁半径。弯道的内侧与外侧壁(即压力面与吸力面)用钢板制成。另外两壁分别用有机玻璃和光学玻璃制成,有机玻璃壁可拆下以清理弯道。

关 键 词:两相流  管道流  激光测量

Abstract:Laser Dopplcr vclocimcter measurements of gas-particle flows are made in a curved duct with strong curvature. The velocity distribution of the solid phase on each cross-section of the duct is flat, but is lower than that of the gas vclocity.It is observed that- the solid phase has remarkable influences on the tangential and radial velocities of the gas phase.
Keywords:two-phase flow   duct flow   laser measurement.
