Abstract

In this thesis, the density currents in a rectangular sedimentation tank are investigated. Experimental studies were made of the flow under different conditions of geometry, momentum and buoyancy. A mathematical model was developed to simulate the characteristics associated with the denser wall jet condition. The experimental program involved temperature tests, flow visualization dye tests and fluorescent dye tests. The variables in the experiments were flowrate, gate opening, weir height, ambient fluid temperature and influent temperatures in the initial tank. Both denser wall jet and buoyant surface jet conditions were considered. The characteristics depths, velocity and temperature of the jet and moving internal hydraulic jump were determined. The mathematical model developed was divided into two parts: a jet submodel and a moving internal hydraulic jump submodel. An equation was developed to relate the submerged depth to the initial depth and sequent depth of the submerged internal hydraulic jump. The mathematical model results are compared with the experimental data for the jet, moving internal hydraulic jump and the submerged hydraulic jump.Dept. of Civil and Environmental Engineering.
