Modeling the Hydrodynamics of Slug Flow in a Minichannel for Liquid-Liquid Two-Phase System

摘要

The hydrodynamics of a Taylor flow in minichannels for a liquid-liquid system is modeled. As a result of solving an inverse problem, a relationship is derived for calculating the thickness of a film around the droplets of the dispersed phase from the velocity of the dispersed phase and the true volume fraction of the dispersed phase is calculated. The adequacy of the model is verified by experimental studies over a wide range of capillary numbers (Ca = 0.05-0.7).
