Abstract:

The kinetic energy density, k, and lifetime, t, of a turbulent eddy, volume V, are shown to be related to a characteristic length scale, 2, by: 13 =vk= c2/3e2/3 t-C 1/312/3 where c is the energy dissipation rate. A self similar cascade of discrete eddy sizes is derived, each size related to the next larger by: P 22 CC i+l i where C= 81'2. With some simple assumptions as to the turbulent production process the mean logarithmic velocity profile is derived. The relationship between the friction velocity and Reynolds stress is explained in terms of the large eddy intermittency, n. Below a critical

Abstract:

This thesis presents a study on the production of microbubble dispersions from rhamnolipid biosurfactant and the mechanism and factors that impact upon the effectiveness of the dispersion for improving bioremediation efficiency, with a specific focus on the use of microbubble dispersion as a carrier for contaminant-degrading bacteria within a bioremediation scenario. Microbubble dispersion is a suspension of a large number of minute spherical gas bubbles encapsulated in a soapy liquid film in an aqueous surfactant solution. Microbubble dispersion has promising potential for enhancing in

Abstract:

Our ability to predict solute transport in groundwater is limited by our imperfect understanding of the physical processes governing the spreading of underground contaminant plumes beneath the surface. Inaccurate prediction of solute migration can in turn result in unreliable risk analyses, or higher costs for groundwater decontamination. It is generally accepted that spatial variations in the hydraulic conductivity of porous materials largely contributes to the spreading of solutes dissolved in groundwater. Unsteady hydraulic gradients can also enhance this dispersion by imposing an additiona

Over fifty small sinkholes (~1 meter in depth and width) were found in conjunction with structural damage to homes in an area south of Cleveland, TX.

However, the site lacked the significant hydraulic gradient or exit points for sediment associated with traditional piping erosion.

Abstract:

Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments. Reducing nutrient loading is a top political priority but the present situation is believed to require active measures within the catchments and recipients to reduce both loading and adverse effects. Implementation of effective and cost-efficient abatement methods requires understanding
