Fall 2012
The problem of low dissolved oxygen (DO) level has been found to be widespread in ice-covered or polluted rivers. This thesis is targeted at providing some fundamental studies on the remediation measure of injecting air/oxygen via existing effluent diffusers to increase river’s DO level, with two...

Fall 2014
Buoyancy driven flow between two finite zones containing fluid of slightly different density is investigated. Two zones separated by (i) a single common doorway, and, (ii) top and bottom vents. In the former case, a two-layer exchange flow develops once the barrier is removed. In the zone that...

This research investigates radially spreading intrusion created from a forced plume, when fluid continuously injected vertically from a nozzle entrains uniformly stratified ambient as it falls back upon itself. The flow evolution is determined as it depends upon the ambient buoyancy frequency,...

Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they propagate up a rising slope in uniform and two-layer stratified ambients. In the case of uniform ambients, the gravity current front decelerates in a nearly uniform...

An analytical and experimental study of boundary gravity currents propagating through a two-layer stratified ambient of finite vertical extent is presented. The theoretical discussion considers slumping, supercritical gravity currents, i.e. those that generate an interfacial disturbance whose...

The Kelvin-Helmholtz instability is the inertial destabilization of a parallel shear flow in a density stratified fluid under the influence of gravity. For example, this type of instability manifests itself as surface waves in the ocean when wind blows over the water surface. In this thesis we...

This research presents the results of two interrelated sets of experiments examining the dynamics of plumes and fountains in two-layer and continuously stratified environments. The first study examines the evolution of an axisymmetric turbulent fountain in a two-layer stratified environment....

We examine the transient evolution of a negatively buoyant, laminar plume in an emptying filling box containing a uniform porous medium. In the long time limit, τ→∞, the box is partitioned into two uniform layers of different densities. However, the approach towards steady state is characterized...
