Dynamics of buoyant releases in confined spaces.
The flows that may result from the release of a buoyant fluid from a small source in a confined space are varied and complex, depending on the source characteristics, the confining geometry and container ventilation. Previous work has generally been based on the 'filling-box' model (Baines & Turner …

Modeling buoyant droplet plumes in a stratified environment
… driven by the continuous release of dissolving buoyant droplets from a fixed point in a stratified, stagnant environment. Model development is motivated by a specific application, the injection of CO 2 into the deep ocean by means of a buoyant droplet plume. This application is one method of …

Turbulent Simulations of a Buoyant Jet-in-Crossflow
A lack of complex analysis for a thermally buoyant jet in a stratified crossflow has motivated the studies presented. A computational approach using the incompressible Navier--Stokes equations (NSE) under the Boussinesq approximation is utilized. Temperature and salinity scalar transport equations …

Submesoscale eddies and their potential for buoyant microplastic accumulation
… seek to understand potential ways in which buoyant microplastics can be re-distributed at depth by eddies characterized by an overturning circulation in addition to an azimuthal circulation. To this end, I conduct a laboratory experiment characterizing the evolution of buoyant microsphere …

Radial spreading of vertical buoyant jets in shallow water
… shallow water bodies. Often these effluents are buoyant with respect to the receiving environment. In many jurisdictions, regulations require that a certain dilution is achieved within a specified mixing zone. In shallow water it is likely that a portion of this dilution will have to be achieved …

Label-free buoyant mass assays with suspended microchannel resonators
… their presence can thus be quantified by their buoyant mass, or increase in mass relative to the solution they displace. This thesis presents two approaches to conducting label-free, buoyant-mass immunoassays with SMRs with potential for clinical applications. The sensor surface can be …

Hydrodynamic modeling of towed buoyant submarine antenna's in multidirectional seas
… the exposure statistics of a radio frequency buoyant antenna as it is towed in a three-dimensional random seaway. The model allows the user to prescribe antenna properties (length, diameter, density, etc.), sea conditions (significant wave height, development of sea), tow angle, and tow speed. …

Modular Modification of a Buoyant AUV for Low-Speed Operation
… planes are typically trimmed to be somewhat buoyant or heavy in water. To maintain depth, they must generate a constant hydrodynamic force which requires that they swim at a constant pitch angle. Although tail fins are the typical mechanism for generating this control moment, they become …

Control design and energy optimisation of a buoyant airborne wind turbine
… optimisation for a specific AWES known as the Buoyant Airborne Wind Turbine (BAWT). There are three key contributions within this work. Firstly, a comprehensive literature review of different airborne systems is provided with specific consideration given to power optimisation and dynamic …

Subgrid Scale Modeling for Large Eddy Simulation of Buoyant Turbulent Flows
… which is being increasingly used for simulating buoyant turbulent flows, requires accurate modeling of the subgrid sclae (SGS) momentum and buoyancy fluxes. This thesis presents a series of LES and direct numerical simulation (DNS) studies towards a priori and a posteriori evaluation of existing …

An Experimental Study of Single and Multiple Turbulent Buoyant Jets in Crossflow
The phenomenon of turbulent, buoyant jets in crossflow is a fundamental fluid mechanics problem with many application areas, including jets discharged from natural and mechanical draft cooling towers. Buoyant jets have been studied for many years, and as a result there exists a large body of …

On convective penetration of a buoyant plume into a stably stratified layer
The convective penetration of a buoyant plume from a uniform layer into an overlying stably stratified layer is relevant to a wide variety of geophysical and industrial flows. An example we focus on is the hydration of the tropical lower stratosphere (TLS) by overshooting deep convection in the …
