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.
Enhancing passive cooling using flexible baffles. The project aims to develop a novel passive strategy using fluid-structure-thermal interactions to enhance passive cooling by natural convection and improve the energy efficiency of engineering systems. Comparing to the existing strategies, the new strategy does not require driving fan or pump and is quiet, reliable, self-adaptive and economical. The Multiphysics embodied in the proposal is at the leading edge of the field. Expected outcomes incl ....Enhancing passive cooling using flexible baffles.

Large Scale Natural Convection Boundary Layers with Non-Boussinesq Effects. This proposal aims to understand and predict heat transfer by turbulent natural convection in two scenarios, firstly at very large environmental scales, such as occur on melting Antarctic ice sheets, and secondly convection involving very large temperature differences such as occur in solar thermal power plants and industrial processes.

This proposal aims to understand and predict heat transfer by turbulent natural convection in two scenarios, firstly at very large environmental scales, such as occur on melting Antarctic ice sheets, and secondly convection involving very large temperature differences such as occur in solar thermal power plants and industrial processes. These natural convection flow regimes are incredibly difficult to investigate directly but by focusing on the fundamental dynamics of the turbulent flows using large scale numerical simulations and innovative experiments, the project is expected to develop better analytical and computational models which will underpin improvements in
global ocean models and improve energy efficiency.Read moreRead less
Reducing the energy consumed by lighting with gaze-dependent illumination. Lighting consumes approximately 18% of electricity, but only a fraction of the light emitted into buildings actually supports occupants’ vision – the rest is wasted. This research aims to reduce the energy consumed by lighting by developing strategies for illuminating only the portions of architectural environments that are visible to occupants, thereby reducing unnecessary light. The impacts of gaze-dependent lighting on ....Reducing the energy consumed by lighting with gaze-dependent illumination. Lighting consumes approximately 18% of electricity, but only a fraction of the light emitted into buildings actually supports occupants’ vision – the rest is wasted. This research aims to reduce the energy consumed by lighting by developing strategies for illuminating only the portions of architectural environments that are visible to occupants, thereby reducing unnecessary light. The impacts of gaze-dependent lighting on energy consumption and the visual environment will be characterized and design guidelines will be generated to facilitate the development of innovative lighting systems that consume less energy by producing less light, without negatively impacting the visual experiences of building occupants.Read moreRead less

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
Advanced all-Iron flow batteries for stationary energy storage. Iron flow batteries are one of the most promising choices for clean, reliable and cost effective long-duration energy storage.

Iron flow batteries are one of the most promising choices for clean, reliable and cost effective long-duration energy storage. The main obstacle for large scale commercial deployment is the low round-trip energy efficiency caused by the competitive side reaction that occurs at the negative electrode during battery charging. The project aims to address this issue by engineering the negative electrode-electrolyte interface with functional materials to improve battery performance and thus further reduce the cost of energy storage.
