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.

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

Natural convection induced exchange flows between near shore and central regions of reservoirs. Inland discharges into reservoirs often carry rich nutrients, pollutants and biological species into the coastal regions, which are redistributed across the central regions of reservoirs through dynamical mixing processes. One of the important mixing processes is the horizontal exchange flow between the near shore and central regions induced by diurnal heating and cooling through the water surface, wh ....Natural convection induced exchange flows between near shore and central regions of reservoirs. Inland discharges into reservoirs often carry rich nutrients, pollutants and biological species into the coastal regions, which are redistributed across the central regions of reservoirs through dynamical mixing processes. One of the important mixing processes is the horizontal exchange flow between the near shore and central regions induced by diurnal heating and cooling through the water surface, which is classified as a natural convection process. This process will be investigated in this project through a closely linked analytical, experimental and numerical research program. The output from this research will have direct application in water quality management and environmental planning.Read moreRead less

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.
3D Hypersonic Shock-Turbulent-Boundary-Layer Interactions. Shock-wave turbulent-boundary-layer interactions occur on hypersonic flight vehicles and can lead to high heating and increased drag. This is a paramount design issue that needs addressing. We aim to understand and quantify fundamental phenomena occurring in such interactions using state-of-the-art instrumentation and wind-tunnel facilities. Surfaces will be heated to realistic flight temperatures to simulate accurately the flight enviro ....3D Hypersonic Shock-Turbulent-Boundary-Layer Interactions. Shock-wave turbulent-boundary-layer interactions occur on hypersonic flight vehicles and can lead to high heating and increased drag. This is a paramount design issue that needs addressing. We aim to understand and quantify fundamental phenomena occurring in such interactions using state-of-the-art instrumentation and wind-tunnel facilities. Surfaces will be heated to realistic flight temperatures to simulate accurately the flight environment and include effects not reproduced with cold models. The effects of 3D features of the interactions will lead to new understanding of how the flow develops through a combination of experiments and numerical simulations. Future designs of hypersonic flight vehicles will benefit from knowledge gained.Read moreRead less
Regulation of the EphA3 receptor tyrosine kinase in vertebrate development. The Eph/ephrin system has a critical role in normal embryonic development.

Multicomponent gas counter-diffusion in coal. Coalbed methane resources in Australia surpass $20billion at present gas prices. Using CO2 as an enhancement fluid, recovery of methane can potentially be improved by 50% adding a further $10b value, simultaneously permanently and safely sequestering the CO2, with possible carbon credits of up to $15b.
