The aim of this project is to improve the understanding of the complex heat transfer processes in evacuated tubular solar water heaters. This project will develop thermal and hydrodynamic models for advanced solar water heaters incorporating evacuated tubular absorbers and will assess the accuracy of the models through a series of outdoor experiments on prototype evacuated tubular solar water heaters. The outcomes will lead to the design and manufacturing of more efficient solar collectors, which can greatly benefit both Australian domestic and export markets.Read moreRead less
Research into techniques for enhancing the heat transfer performance of finned-tube heat exchangers. This project explores several methods for enhancing the heat transfer performance of mechanically bonded finned tube heat exchangers. The methods would be analysed experimentally, and using finite elements, numerically. Any increase in heat transfer efficiency would contribute to the conservation of energy, and therefore, of natural resources. An improved design of heat exchangers would give a de ....Research into techniques for enhancing the heat transfer performance of finned-tube heat exchangers. This project explores several methods for enhancing the heat transfer performance of mechanically bonded finned tube heat exchangers. The methods would be analysed experimentally, and using finite elements, numerically. Any increase in heat transfer efficiency would contribute to the conservation of energy, and therefore, of natural resources. An improved design of heat exchangers would give a definite competitive edge to the Australian manufacturer. An equally significant outcome would be the training of a research person in industry-related research and skilled both in experimental and numerical procedures.Read moreRead less
Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. 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 ....Entrainment and Mixing in Turbulent Negatively Buoyant Jets and Fountains. 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
