Summary
New mathematical theory for fluid motion on surfaces with holes. This project aims to develop new explicit mathematical results to enhance the understanding of potential theory – a fundamental area of mathematics - on surfaces with complicating geometrical properties. There are very few such fundamental results on complicated curved surfaces, such as those with holes. This project should provide a toolbox for solving many different mathematical problems on curved surfaces. The new results should ....New mathematical theory for fluid motion on surfaces with holes. This project aims to develop new explicit mathematical results to enhance the understanding of potential theory – a fundamental area of mathematics - on surfaces with complicating geometrical properties. There are very few such fundamental results on complicated curved surfaces, such as those with holes. This project should provide a toolbox for solving many different mathematical problems on curved surfaces. The new results should also have application to the analysis of fluid flows over porous media and practical engineering structures.Read moreRead less

An Investigation Into Fountains Interacting With Both Free Surface and Solid Boundaries. This project will produce an improved understanding of the behavior of fountains interacting with both free surface and solid boundaries.

Such flows occur in many environmental and industrial processes and, in particular, the interaction of fountain with boundaries will have a significant influence on the overall performance of the processes. This investigation will combine experiments, numerical simulations and scaling analysis to provide new insight into the physics governing the behavior of these impinging fountains. Turbulence models will be developed and validated and scaling formulae will be obtained providing relationships for the basic flow properties in terms of the control parameters.Read moreRead less
Enhancing natural convection heat transfer using a single horizontal non-metallic fin. This project will develop the basis for a simple design to improve the energy efficiency of natural convection heat exchangers. Heat exchangers are widely adopted in many electronic devices and industrial processes as they require no external power input, additional space, and are quiet, reliable and economical. The research will exploit the interaction between two flows to trigger turbulence, and will result ....Enhancing natural convection heat transfer using a single horizontal non-metallic fin. This project will develop the basis for a simple design to improve the energy efficiency of natural convection heat exchangers. Heat exchangers are widely adopted in many electronic devices and industrial processes as they require no external power input, additional space, and are quiet, reliable and economical. The research will exploit the interaction between two flows to trigger turbulence, and will result in an increase of the overall capacity and performance of engineering systems. This will contribute significantly to reductions in power consumption and improvements in productivity and work environment, leading ultimately to reductions in greenhouse gas emissions and to economic benefits.Read moreRead less
Transport by Natural Convection in Reservoir Sidearms. This project is a first step in developing models of the distribution of water quality parameters in reservoirs by a range of small scale dynamical processes not included in commercial water quality models. Specifically, the project will investigate the transport of suspended materials from the shore to the deeper parts resulting from the interaction of the meteorological forcing and the topography. This will contribute to the development of ....Transport by Natural Convection in Reservoir Sidearms.

Conjugate natural convection boundary layers. Conjugate natural convection systems occur when a conducting vertical wall separates fluids at different temperatures (that is at a window separating the interior of a room from the outside or when a container of fluid is placed in a refrigerator). This project will provide accurate predictions of such flows together with scaling relations.

The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.Read moreRead less
