The Effect of Bubbles on Particle Migration in Non-Newtonian Fluids

The movement of the gas–liquid interface caused by bubble position will have an impact on starting conditions for particle migration. This article quantifies influence moving bubbles migration in non-Newtonian fluids, and it aims to better understand fluids achieve more effective control. First, forces moments acting particles are analyzed; then, fluid dynamics, mechanics, extended DLVO (Derjaguin Landau Verwey Overbeek theory), surface tension, friction applied combined effects Then, we reasonably predict fluids. theoretical results show that increase separation force particles, which lead Second, carry out experiment fluid. Experiments when solid–liquid two-phase flow is originally stable, occurs after added. phenomenon shows with motion has stronger ability. Although there some errors, experimental basically support data.
