摘要： 为提高微尺度下不同反应物的混合效率,针对Y型脉动微混合器结构与工作参数对其混合性能的影响展开优化研究。采用仿真分析对微混合器流道截面尺寸、入口夹角、入口流量及脉动频率进行了优化分析,优选出最佳结构和工作参数,并以此制作试验用系统样机;利用化学反应探针法,通过检测可控合成后的金纳米粒子大小及分布情况,综合评估其混合性能。试验结果表明:Y型脉动微混合器的截面尺寸、流道夹角在入口流量及工作频率一定的条件下存在一个最优值,入口流量及工作频率是一对相互影响的重要工作参数,一定的流量对应一个最佳混合频率。

Abstract: In order to improve the mixing efficiency of different reactants in microscale, a study on optimization of the structure and working parameters of the Y type pulsing micro mixer is conducted, in which the effects of the structure and parameters on mixing performance are taken into consideration. By simulation analysis, the channel section size, entrance angle, entrance flow rate and pulsation frequency are optimized. Based on the optimized structure and working parameters, a test prototype was made in lab. Using chemical reaction probe method, the prototype is tested. After detecting the size and distribution of gold nanoparticles by controllable synthesis, the mixing performance is evaluated synthetically. The test results indicate that when the entrance flow rate and working frequency are ascertained, there exist corresponding optimum values of the section size and flow rate of the Y type pulsing micro mixer. The entrance flow rate and working frequency are important parameters which influence each other. A certain flow rate corresponds to an optimum mixing frequency.
