摘要
从高压微射流超细粉碎的作用机理、微孔流道形式对其粉碎效果的影响两个方面对高压微射流超细粉碎技术进行了研究。用FLUENT软件对流场进行数值计算模拟,得到了微射流流场内各位置上相关物理量的分布情况,得出带撞击形式的微孔流道更有利于得到更强的作用力场,也更能保证高压微射流粉碎作用效果的结论。
The technology of super-fine grinding based on high pressure microfluidics was studied in two aspects, which were the mechanism of it,the influence of the micro-channel to grinding effect and the testing effect of the equipment. Using FLUENT software, the liquid flow-field and get the pressure and force distribution of it were modeled and computed. The result showed that the micro-channel with impinging stream shape could get more tremendous force and ensured that the equipment get perfect effect.
