Numerical simulation and optimized design of rhombic micromixers

In this paper, we used rhombic units to design micromixers. The influence of rhombic angles, width ratios, and the shapes of internal microchannels on mixing performance were studied. The simulation results were calculated in the range of Reynolds number (Re) 0.5 to 100. We mainly studied the mixing...

Description
Summary:In this paper, we used rhombic units to design micromixers. The influence of rhombic angles, width ratios, and the shapes of internal microchannels on mixing performance were studied. The simulation results were calculated in the range of Reynolds number (Re) 0.5 to 100. We mainly studied the mixing performance of rhombic micromixer from three aspects, including mixing efficiency, pressure drop, and fluid behavior in the microchannels. We used COMSOL Multiphysics 5.2a to simulate and calculate. The final optimized micromixer had a high mixing efficiency of more than 91.9% at all flow velocities.
