T型微通道制备可控粒径SiO2微球的数值模拟
Controlled preparation of SiO2 particles in T-junction microchannel by simulation and experiment
摘要
Abstract
A numerical simulation was processed to investigate the main factors of droplet diameter formatted in the T-junction microchannel,and to verify from the experiment.The results showed that the main factors influencing droplets diameter were the geometry ratio of discrete phase inlet and the continuous phase inlet (2＜l＜10) as well as the velocity ratio (4＜k＜16),silicon particles with diameters of 50,80,120 μm (l=5,k=4,6,10) reached spherical degree above 93％,monodispersity,CV ＜5 ％ of statistics.In conclusion,the numerical simulation and experiment were in good consistency.关键词
