Three-Dimensional Modeling of Density Current in a Straight Channel
Publication: Journal of Hydraulic Engineering
Volume 135, Issue 5
Abstract
Dense underflows are continuous currents that move downslope due to their density being heavier than that of the ambient water. In this work, a steady density current with a uniform velocity and concentration from a narrow sluice gate enters into a wide channel of lighter ambient fluid and moves forward downslope. Experiments varying inlet velocity and concentration and hence inlet Richardson numbers were conducted. Numerical simulations were also performed with a low-Reynolds number model. The results of numerical simulation agree well with the experimental data.
