A Comparative Study of Mixed Resolved–Unresolved CFD-DEM and Unresolved CFD-DEM Methods for the Solution of Particle-Laden Liquid Flows

Abstract

The exorbitant economic and environmental cost associated with fouling propels the need to develop advanced numerical methods to accurately decipher the underlying phenomena of fouling and multiphase fluid transport. The objective of this research is to numerically examine the transient evolution of particle-laden liquid flow and particle accumulation (fouling) based on two numerical approaches: unresolved finite volume-discrete element method (FVM-DEM) and Brinkman penalization to examine transient particle-fluid transport and fouling. The efficiency of both numerical methods are compared and etc.... The results obtained by both numerical methods are then compared against experimental results. Results have shown that the two methods, etc.
