This study presents a simple design for micromixers based on the concept of cantor fractal structures. This fractal structure is composed of different shapes of mixing units for folding and chaotic advection in fluid flow. Three designs known as YSUSAR, YTUSAR, and YSTUSAR are analyzed and characterized by concentration, velocity contours, line plots of Reynolds number versus mixing index, and the Reynolds number against pressure drop. The designs are fabricated on glass by a 3D multi-head printing system and tested experimentally for mixing performance. The results demonstrate that YSUSAR has a better mixing performance than the other two proposed designs.

基于Cantor分形结构的三种Y型分离重组混合器的实验与数值分析。

这项研究基于坎托分形结构的概念提出了一种用于微混合器的简单设计。这种分形结构由不同形状的混合单元组成,用于流体流动中的折叠和混沌对流。通过浓度,速度轮廓,雷诺数相对于混合指数的线图以及雷诺数相对于压降的分析,表征和分析了三种设计,分别称为YSUSAR,YTUSAR和YSTUSAR。这些设计是通过3D多头打印系统在玻璃上制成的,并进行了混合性能的实验测试。结果表明,YSUSAR具有比其他两个拟议设计更好的混合性能。
