Mathematical modeling of segmented flow in microchannels
Original language description
The multiphase flow, where reaction-transport processes are limited by diffusion, is involved in many industrially important chemical processes. Microreactors based on multiphase flow have emerged in the last few years. More recently, the attention focuses on immiscible liquid-liquid systems at microscale, where intensification of reactions is achieved by segmentation of the fluids. Vortex flow patterns within the fluid segments enhance mixing and improve mass transfer across the interface. Here we present a mathematical model of a representative part of the microfluidic channel with two liquid phases. In case that the reaction is not accompanied with a substantial change of the volume of liquid phases, the problem can be split into a hydrodynamic partand a reaction-transport part. Mathematical description of the hydrodynamic problem is based on the Navier-Stokes equation or the Stokes equation and the continuity equation for each liquid phase together with relevant boundary condition
