Represents the simulation results along the mixing channel of all the four designs at Q = 6 µL·min−1, Re ~ 4.7 in pre-mixer and ~ 20 in ring-shaped units. (a) side view of the mixer pattern A with position marks in the main mixing channel and in the ring-shaped mixing zone. (b) Mixing index data obtained by simulation of the evaluated sample for all four cases in Fig. 4, same conditions were applied. The concentration data chosen here for the mixing indices calculation were extracted from the concentration profile projected onto the z–y plane at the locations labelled 1–6 on the mixing channel of panel (a). (c) shows the slice concentration profile projected onto the z–y plane at the locations labelled A–F on the mixing channel of panel (a), with the distributions of the velocity vectors overlayed on the same profile. The color bars for the concentration profile are presented besides, with the concentration ranging from 0 to 10 × 10–4 mol·m−3. The simulations were performed with the COMSOL Multiphysics software (https://www.comsol.com).
