Determination of the average size,concentration and velocity of the particles in the multiphase flows

摘要

This paper describes the principles for determinign the average size,concentration and velocity of the particles in the gas-solid two-phase flow,the average size and ocnentration are determined from the flucturation fo transmitted light,and hte velocity from correlation analysis.An apparatus based on these principles is constructed,and used to determine the size and concentration of the latex spheres as SRM as well as the velocity of the wires fitted on a disc driven by a motor,The experimental results show that the presented method is reliable and prepeatable.
