Flows driven by the application of a horizontal temperature gradient has applications in nature and engineering. Although much progress has been made in the analysis of the case of a sudden application of temperature differences to the vertical walls of a container with insulating horizontal walls containing an isothermal fluid, the reality is that neither the insulated walls nor the initially isothermal fluid can be achieved. This project will, by analytical, numerical and experimental methods, make a preliminary investigation of the influence of conducting horizontal walls and an initially stratified fluid.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

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

This project aims to create a specialised acoustic levitation facility that delivers precise control of a suspended particle/droplet/bubble within a high pressure continuous phase, and simultaneous measurement of multiple bulk and interfacial properties. Acoustic levitation enables container-less experiments, offering opportunities for applied engineering and fundamental science. This acoustic levitation system will be integrated with a specialised Raman imaging microscope to study crystallisation, mass transfer and molecular exchange, in application areas including energy transport, carbon capture and storage, and protein nucleation. This project is expected to open new avenues in engineering, chemistry and physics.Read moreRead less
Fluid Transport in Materials of Nanoscale Dimensions. This project aims to transform the modelling of fluid transport in materials of nanoscale dimension by determining the coupled interfacial heat and mass-transfer barriers, which critically influence the transport. The outcome will not only be new knowledge on the effects of inherent structural distortion and of the barriers on the fluid flow, but also cutting-edge techniques to estimate system size-dependent transport coefficients in nanoscal ....Fluid Transport in Materials of Nanoscale Dimensions. This project aims to transform the modelling of fluid transport in materials of nanoscale dimension by determining the coupled interfacial heat and mass-transfer barriers, which critically influence the transport. The outcome will not only be new knowledge on the effects of inherent structural distortion and of the barriers on the fluid flow, but also cutting-edge techniques to estimate system size-dependent transport coefficients in nanoscale systems. These will be achieved through a combination of targeted molecular dynamics simulations and experiment, and will have far-reaching implications for nanotechnology and emerging processes in catalysis, gas separation, human health and nanofluidics, and enable design of more efficient systems.Read moreRead less
