Mathematical model of the process of mixing and separation in a microfluid channel with five outlets

Abstract The article presents the results of mathematical modeling in a two-dimensional formulation mixing process by mutual diffusion and separation flows Newtonian fluids microfluidic channel with five outlets. Branches are used to separate into fractions given concentration one components mixture. occurs laminar flow regime, without chemical thermal interaction. mixture model was set up formulation. One component through main 1 mm wide, then at distance 5 from entry point perpendicular it, there two more entrances also which second is fed. At outlet, taps dimensions 0.2 take desired concentration. Four outlets for intake located opposite each other pairs. Liquids physical characteristics water ethyl alcohol were taken as miscible components. problem solved using ANSYS-Fluent software package.
