Mixing Analysis in A Three-Dimensional Serpentine Microchannel

초록

A computational fluid dynamics technique has been applied to understand mixing phenomenon in three-dimensional serpentine microchannel. The special shape of the serpentine geometry with “L-shape” repeating unit is found to be very effective in mixing the two fluids. Dependence of mixing on the various design parameters has been analyzed at four Reynolds number with the aim to achieve effective mixing of the fluid in a minimum dimension. Both qualitative and quantitative analysis has been performed to understand the mixing behavior with the design parameter. Pressure drop characteristic with the design variable has been reported. The results presented provide an information to design effective micromixer in a minimum dimension.
