摘要

气泡、液滴大小及概率密度分布对研究气液及液液两相流设备中的能量传递、反应过程以及设备和工艺的最优化设计等

具有十分重要的意义.以往

测量液滴、气泡大小分布主要采用照相法、化学法、电阻探针法等

这些方法应用范围窄

或者费时长、精度低.

Abstract

A microcomputer aided system with the use of a photoelectric capillary probe is used for on-line automatic measurment of gas bubble

liquid drop and foam size distribution in two-phase flow. The experimental results were calibrated for the pressure in the capillary probe. The system works well with the advantage of high accuracy

high speed

and simple operation. In this paper

the principles of the technique are put forward

the hardware disposition and the software for sampling and handling data in the microcomputer aided system are introduced. Finally

the method of calibration and some results of measurement are presented.
