Thermal enhancement strategies and development of a high-performance micro-scale heat exchanger for thermoelectric refrigeration with large cooling loads. Traditional refrigeration essentially utilises CFC-refrigerants which are potent atmospheric pollutants causing widespread ecological damage. Devoid of such adversities, electronic heat pumping mechanism of thermoelectric principle offers a practical ?CFC-free? alternative for conventional cooling methods.

Traditional refrigeration essentially utilises CFC-refrigerants which are potent atmospheric pollutants causing widespread ecological damage. Devoid of such adversities, electronic heat pumping mechanism of thermoelectric principle offers a practical ?CFC-free? alternative for conventional cooling methods. While the current thermoelectric technology adequately meets light cooling demand, its potential for heavy-duty refrigeration is critically undermined by ill-developed methods for dissipating heat from thermoelectric modules to coolants, and remains grossly under-utilised. The proposed work will devise novel heat transfer techniques for raising thermoelectric cooling thresholds to suit large heat loads and develop a thermally enhanced micro-scale heat exchanger for application in commercial thermoelectric refrigeration.Read moreRead less

This project will address the important need for a highly effective lightweight coating. Different interlayers of bio-retardants derive from organic compounds and two-dimensional sheet-like nanomaterials are fabricated to enhance the charring, thermal barrier and flammability resistance. Molecular dynamics are adopted to deliver more targeted fabrication to achieve increased efficacy of the engineered interlayers and provide important insights on the combustibility of polymers undergoing mass diffusivity, thermal diffusion and oxidation process at high temperatures. Expected outcomes of the project are lightweight coated polymers possessing elevated resistance to fire with a significant reduction of toxic gas emissions and smoke releases. Read moreRead less

Heat Transfer Characteristics of Biological Tissues with Nanoparticles. Heat transfer of laser-irradiated nanoparticles in biological tissues requires a basic knowledge of the unique strong resonance absorption properties and a fundamental understanding of the thermal and chemical conversions as a consequence of these heated nanoparticles.

Heat transfer of laser-irradiated nanoparticles in biological tissues requires a basic knowledge of the unique strong resonance absorption properties and a fundamental understanding of the thermal and chemical conversions as a consequence of these heated nanoparticles. This project aims to investigate the extent of the non-equilibrium heating effects of heated nanoparticles on the destruction of biological tissues. Comprehensive experimental studies and computational modelling to be performed are expected to significantly enhance the understanding of laser-induced heating phenomena of embedded nanoparticles in biological tissues and the prediction of the level of destruction that can be experienced by these heated nanoparticles.Read moreRead less
