ABSTRACT

Low amplitude wavy channel micromixers have been studied for mixing performance using Computational Fluid Dynamics (CFD). A number of simulations for T-Junction straight channel, T-Junction wavy channels, and T-Junction wavy channels with different obstacles were carried out. Detailed flow and mixing field analysis was conducted to understand the flow and mixing phenomenon. The two important characteristics, the mixing efficiency, and the pressure drop, were studied for Reynolds numbers ranging from 0.1 to 75. The effect of channel shape, obstacle geometry, and length of the channel has been studied through visualization of the mixing field and quantitative comparison of the mixing index and the pressure drop.
