Journal Article on Contact Tank Efficiency

Together with co-authors from Colorado State University, Alden’s Zach Taylor has published an article in the Journal of Hydraulic Research. The article discusses the use of Computational Fluid Dynamics (CFD) to design baffles in contactor tanks. 

In particular, the study addresses the question:

For a given footprint of a rectangular tank with a specified inlet width, how does the hydraulic efficiency of a baffled tank depend on the configuration of internal baffles?

A parametric study consisting of 30 high-resolution two-dimensional simulations was conducted to quantify the hydraulic efficiency of a laboratory scale tank as a function of dimensional relationships between key baffle design dimensions (baffle opening length, baffle channel width, and baffle channel length).

The results indicate that the hydraulic efficiency can be optimized by ensuring that the baffle opening length is equal to the channel width, and orienting baffles along the longer direction of the rectangular footprint.
