Numerical Analysis of Merging Flows of Floc-Forming Fluids in a T-Junction Channel Using a Non-Newtonian Viscous Model Based on a Population

The flow of a floc-forming fluid in T-junction channel was numerically analyzed using non-Newtonian viscous model based on the population balance equation (PBE) floc size. finite element method applied to solve velocity and pressure fields, PBE size distribution computed obtain effective volume fraction flocs. Krieger-Dougherty used evaluate viscosity suspension flocs fraction. numerical simulation captured characteristic aggregation-breakage behavior flow. In region where flows from two entrances merge, decreases because breakage progresses. downstream channel, re-aggregation occurs near centerline, increases. This confirmed by analysis distribution.
