| 摘 要： | 本文发展了一种同时测量两相流中固相和液相速度的方法。在通用的双光束LDV 基础上,采用前后向散射接收和门控、幅值鉴别和直方图鉴别等功能实现两相速度信息的区分。应用此系统测量了二维收缩、扩张管道中两相流动的速度分布。

| Abstract: | A method for measuring all together the solid and liq-uid phases velocities in two-phase flow has been developed.Based onthe using of conventional 2-beams LDV system operated in forward andbackward scattered modes together with the functions of gating control,amplitude and histogram identifications the velocity information dis-crimination between two phases can be realized.The velocity distribu-tions of two-phase flow in a 2-D convergent/divergent duct were alsomeasured successfully. |
