Abstract
A numerical procedure is presented which allows one to predict the depositi on rate of microparticles suspended in a liquid flow onto the confining wal ls. Particle transport: is nor only diffusive but also affected by hydrodyn amically induced lift force and reduced particle mobility. An appropriate e xpression for the lift-induced migration is introduced into the numerical p rocedure. Its results agree quanititatively with previously published exper imental data showing a significant effect of lift-induced particle transpor t. Based on the numerical results algebraic correlations are obtained, whic h enable to calculate the particle deposition rate in situations where lift forces and mobility reduction diminishes the particle deposition rate.
