Abstract

Over the last two decades, design and fabrication of micromixer have been an emerging trend in research field of microfluidic. Micromixers are generally categorised into two types which are the passive micromixer dependent on pumping energy and active micromixer that relies on external energy to achieve fluid mixing in desired parameters. This paper presents the micromixing simulation of two fluids of different concentrations from two inlets to generate four distinguished concentration gradient of output in four outlets. The blueprint of the micromixer was designed using Solidworks, computer-Aided design software. The 2D model design was imported to COMSOL Multiphysics 4.2 to simulate the fluid mixing. The suggested physic modules were applied on the 2D model to aid the fluids dilution and mixing process. Linear dilution was achieved by applying low flow rates to the micromixer.
