T-shaped micromixers aligned in a row: characterization of the engulfment regime

Abstract Accurate control of mixing between two fluids is a fundamental aspect in many applications and generally implies the use small devices operating at low velocities. This often achieved using micromixers which, due to combination dimensions velocities, work laminar regime process very limited flow rates. The rates can be increased more mixers same time. In this respect it appealing several connected unique device. paper we propose characterize simple strategy connect T-mixers together by aligning them row feeding shared inlet channels. Since engulfment preferred for mixing, investigate proposed specifically focusing on onset properties regime. investigation carried out combined numerical simulation linear stability analysis. results reported here show that lead compact which single manifest engulfment, although some important differences comparison with isolated may exist depending spacing inlet/outlet channels
