摘要

Abstract

The cohesive solids in liquid flows are featured by the dynamic growth and breakage of agglomerates

and the difficulties in the development

design and optimization of these systems are related to this significant feature. In this paper

discrete particle method is used to simulate a solid-liquid flow system including millions of cohesive particles

the growth rate and breakage rate of agglomerates are then systematically investigated. It was found that the most probable size of the agglomerates is determined by the balance of growth and breakage of the agglomerates the cross point of the lines of growth rate and breakage rate as a function of the particle numbers in an agglomerate

marks the most stable agglomerate size. The finding here provides a feasible way to quantify the dynamic behaviors of growth and breakage of agglomerates

and therefore offers the possibility of quantifying the effects of agglomerates on the hydrodynamics of fluid flows with cohesive particles.
