Our personal highlight: Averil Fernandes’ presentation on “Using CFD to optimize wastewater treatment plants”. With vivid examples and practical insights, she showed how numerical flow simulations can make a concrete contribution to making wastewater treatment processes more efficient.

A big thank you to everyone who made this conference possible! And because pictures sometimes speak louder than words, we would like to share a few impressions of the conference with you.

THINK Fluid Dynamix^® is a consulting and engineering service that specializes in advanced numerical technologies, such as Computational Fluid Dynamics (CFD) and automated optimization.

CFD is a powerful numerical technology that uses sophisticated algorithms to simulate and analyze fluid flow in a digital environment. By modeling crucial unit operations such as mixing and homogenization for a variety of fluids and operating conditions, CFD provides valuable insights that help optimize processes, reduce costs, and increase overall efficiency.

In industries like paints and coatings, CFD has become a game-changer, delivering actionable data for process improvements and innovation.

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).
