Abstract

In this paper, the effect of the baffle on the mixing efficiency is studied when the baffle is distributed on the lower surface of the microchannel. The mixing efficiency of the micromixer was analyzed by numerical simulation. To study the change of mixing efficiency of micromixer, we changed the fractal number of baffles, height of baffles, spacing of baffles, angle of baffles, the number of baffles. Through analysis and comparison, we finally chose a micromixer with fractal number of 2, baffle height of 0.2 mm, baffle spacing of 0.25 mm, baffle angle of 45° and baffle number of 15.
