| 摘 要： | 两相流的测量是许多工业装置中遇到的一个十分重要的课题,本文引入了一种新的测量装置。它采用三光束偏振型光路消除了边缘效应,输出信号由计算机软件处理,采用双阁值法方便、有效地对两相流的速度进行测量。适当改进后,本装置能同时对两相流的粒子尺度及粒子速度进行测量。

| Abstract: | A Laser Doppler Velocimeter system is developed for measuring two-phase flow In this system,three polarized beams are used,and the edge effect is suppressed.Output signals are processed by computer.Using two-threshold method,it is easy and efficient to measure ve- locities of two-phase flow.If some improvements are made,it would be possible to measure particle size and its velocity simultaneously. |
