激光角散射诊断气固两相流粒度及浓度的研究

Research on evaluation of air-solid two phase particle distribution and mean concentration by laser scattering

根据Mie散射理论 ,论述了气固两相流颗粒相粒度分布和平均浓度测量的基本原理和试验方法 ,利用氧化铝粉末气固两相自由射流试验台 ,进行了一系列实际测量。

Based on Mie scattering theory,the basic principle and test method to evaluate air solid two phase particle distribution and mean concentration is presented.A series of experiments have been made to prove the theory with the powder of aluminum oxide in an air particle free jet.
