The microchannel reactor is the most commonly used microreaction technology, an innovative reaction system developed in recent years. This study investigates the mass transfer behavior of a gas-liquid two-phase Taylor flow in a microchannel by coupling the volume-of-fluid model and the species transport model. The concentration distribution and the volumetric mass transfer coefficient of the gas solute are determined and discussed in detail. The simulation results reveal that the
Taking CO2/N2 and water as a system, the influence of microchannel inlet structure on the hydrodynamics of gas-liquid two-phase Taylor flow is numerically simulated by using VOF and species transport model. The flow properties of Taylor flow in perpendicular inlet structure are firstly explored, and the simulation results are compared with the inlet structures with different angles. The microchannel inlet structure has an obvious effect on the flow properties of Taylor flow. The simulation results provide some guidance for the design of micro reactor.
