【摘要】 含颗粒两相流的小体积范围内的颗粒数随机变化导致散射光和透射光呈现动态特征,这种光信号动态特征可用来测量两相流的流速、颗粒粒度和浓度。本文介绍两种理论模型并分析比较其优缺点。更多还原

【Abstract】 The scattering light and the transmitted light by particles in a small fraction of volume of the two phase flow show dynamic characteristics due to the random variation of particle number.The dynamic characteristics can be used to measure the flow velocity,the particle size and concentration.In this work,two mathematical models were proposed and the advantages and disadvantages of them are compared.更多还原
