Abstract

In order to improve the performance of the micromixer and increase the mixing index, this research has simulated and investigated the effect of using an electric field using COMSOL Multiphysics software. The proposed case in this work is a 2D T-shaped micromixer with two inlet openings of dimensions 100 μm, and the length of the mixing channel is 1400 μm. The results indicate that increasing the voltage from 0 V to 20 V enhances the mixing index in the micromixer, resulting in improved mixing. Increasing the inlet velocity from 0.2 mm/s to 0.8 mm/s leads to a pressure drop of 124.27%, 249.13%, and 373.41%, respectively. With an increase in the voltage applied by t
