Short Circuiting and Density Interface in Primary Clarifiers
Publication: Journal of Hydraulic Engineering
Volume 120, Issue 9
Abstract
The unsteady flow regime and the temperature mixing in temperature‐stratified settling tanks associated with a warm influent are investigated by application of a numerical model with two different turbulence models. The model consists of a series of conservation equations for fluid mass, momentum, and temperature, with one version using the algebraic stress model and the other version using the conventional model. The simulation results are compared with existing experimental data for the temperature distribution. The velocity measurements were made under the same laboratory conditions that were used for the temperature surveys. The experimental results are presented and compared with those predicted by the numerical model.
