Title: Quantitative Analysis of Velocity Gradients in Rapid Mixing Tanks Using Computational Fluid Dynamics (CFD)
This presentation introduces a novel approach to the analysis and characterization of rapid mixing and flocculation tanks using computational fluid dynamics (CFD) simulations. While rapid mixing chambers, designed for efficient initial contact and dispersion of the flocculant, are characterized by high velocity gradients and short residence times, flocculation tanks require a significantly larger volume, longer residence times, and gentle flow circulation to promote floc growth and aggregation. Traditional engineering practices have often relied on averaged parameters like the G-value (Camp and Stein, 1943) to describe the overall velocity gradient within a tank. However, these conventional methods fall short in providing a detailed understanding of local flow dynamics within the tank.
Using advanced Computational Fluid Dynamics (CFD) simulations, it is possible to conduct a more precise analysis of velocity gradients both locally (Eulerian approach) and on individual flocs (Lagrangian approach).
