Characteristics of Gas–Liquid Slug Flow in Honeycomb Microchannel Reactor

The gas–liquid slug flow characteristics in a novel honeycomb microchannel reactor were investigated numerically and experimentally. Computational fluid dynamics (CFD) modeling was carried out with Comsol finite element software using the phase-field method, simulation results verified by micro-particle image velocimetry (micro-PIV) analysis. breakups of liquid slugs at bifurcations current followed complex behavior, leading to non-uniformity each branch. pressure distribution inside microreactor closely related phase distribution. increasing inlet gas velocity increased volume fraction, as well length. Higher resulted stronger turbulence field deviation residence time from normal distribution, but it favorable even more during phase. There also exists secondary interface. This work reveals intrinsic intensified effect microchannel, provides guidance on future design for chemical energy conversion.
