Micromixing is a crucial phenomenon in micro devices used microfludic applications. There are two basic approaches exploited to induce mixing at the micro scale. Based on the two approaches micromixers are generally classified as passive and active micromixers. Passive micromixers solely depend on pumping energy, however active micromixers depend on external power to achieve mixing. In the proposed study two simple types of passive micromixers namely T and Y-junction micromixers are numerically analyzed by using Computational Fluid Dynamics (CFD) software COMSOL Multiphysics 5.0. The effect of different obstacles on the mixing length and pressure drop is studied with the help of numerical simulations. The simulation results showed that micromixer with rectangular obstacles has the lowest mixing length.
