Computational Analysis of Fluid Flow in Split and Recombine Micro-channel with Circular Obstacles

The microchannel plays a vital role in the microfluidics and have vast application in different areas like Lab-on-a-chip, Micro reactors, micro electro mechanical system (MEMS) biological applications, etc. The mixing in microchannel governs the performance. The computational study of split and recombined micro channels with obstacles is presented in this paper. The computational study of arrow type microchannel is performed by using COMSOL Multiphysics software at different Reynolds number (Re). The sway of the Reynolds number, form, and size of the barriers is reported along with the suggestions regarding the future scope.
