Four passive micromixer designs (G1, G2, G3, and G4) based on distillation columns trays are proposed. The performance of the devices is assessed by numerical simulations. The mixing performance is investigated for different Reynolds numbers and channel heights for oil/ethanol flow. G1 and G4 designs provided a high mixing index. The G1 device achieved superior mixing performance with a moderate pressure drop due to the induced flow recirculation pattern for a relatively high flow rate, highlighting the potential use of such microdevice for scale‐up and numbering‐up of microdevices in modular chemical plant processing.

基于蒸馏塔板的新型微混合器的设计与分析

提出了基于蒸馏塔塔板的四种无源微混合器设计（G1，G2，G3和G4）。通过数值模拟评估设备的性能。针对油/乙醇流的不同雷诺数和通道高度研究了混合性能。G1和G4设计提供了高混合指数。G1设备实现了卓越的混合性能，并且由于相对较高的流速而产生了诱导的流体再循环模式，因此具有适度的压降，突出了这种微型设备在模块化化工厂加工中用于微型设备的放大和编号的潜在用途。
