The calculation study of the mixing efficiency of two fluids in a T-type micro-channel with O-shaped dividing

Abstract

A computational study of the micromixer form influence on the mixing efficiency and pressure drop in a wide range of Reynolds numbers 1 ≤ Re ≤ 300 was carried out. It was found that as the amount of basis elements increases the pressure drop and mixing efficiency also increase in a whole range of Reynolds numbers. The obtained results were compared with a one for the T-type micromixer with direct mixing channel of the corresponding length. The dependence of the relative reduced mixing efficiency on the Reynolds number was obtained. It is revealed that the use of micromixers with a complex geometric shape allows to intensify the mixing processes, especially at low Reynolds numbers.
