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. While the current thermoelectric te ....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. 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

Yield improvement in large-scale bubble column fermenters. For companies operating in the global marketplace, yield differences of a few percent can be critically important. Improving yeast fermentation yield requires major advances in modelling the bubble size distribution and how this impacts micro- and macro-scale mixing. Model-based knowledge transfer via full-scale plant trials is a key outcome.
