Abstract	:	We have designed the interior of a wing-shaped micromixer in such a way that it forces the liquids flowing through it to undergo a combination of the converging and diverging micromixing. In this paper, we have evaluated and compared the response of design parameters on the performance of wing size planar passive micromixers. For this purpose, we have simulated the flow of liquids whose Reynolds number lie in the range between 0.01 and 100, through two micromixers with different design parameters. COMSOL software has been used to execute the finite element analysis based simulation and the resulting mixing efficiency was improved by applying different types of mesh on the geometry of the micromixer. An ultimate mixing efficiency value of 87% with a pressure drop 71. 782 kPa at the outlet of the micromixer has been found for a liquid with a Reynolds number 60. We found that the induced constriction in the flow controls the degree of mixing. The micromixer with a wing size of 100 �m gives better mixing efficiency than the micromixer with 75 �m wings.
