摘要：
A series of high-resolution CFD simulations as well as experiments were implemented to investigate the mixing in single stage and double stage T-shaped micro-channel networks. With Reynolds number increasing from 5 to 200, three different flow regimes, namely stratified flow, vortex flow and engulfment flow were observed. In the single stage T-shaped structure mixing efficiency was intensified only when engulfment flow regime was reached. While in the double stage T-shaped network structure, with contact area increasing and flow direction changing, mixing performance apparently improved after vortex flow appeared in the highest stage. Compared with single stage, mixing in the double stage structure occurred earlier. At the same residence time, mixing efficiency was higher in the double stage T-mixer than in the single stage one. Bionic networks containing multi-stage T-shaped micro-channel greatly enhance micro-mixing, and this kind of network is a powerful micro-mixing configuration. © All Rights Reserved.
