Variable Geometry Cooling Intakes for Passenger Vehicles. Cars reject engine heat via air forced through the grille, radiator and engine bay. The associated "cooling drag" increases total aerodynamic drag by 10-15% hence increasing fuel consumption. The highest heat load that needs to be rejected by the engine determines the quantity of cooling air, resulting in systems that are over designed for typical driving. This research provides a strategy of adjusting the cooling airflow to match the ....Variable Geometry Cooling Intakes for Passenger Vehicles. Cars reject engine heat via air forced through the grille, radiator and engine bay. The associated "cooling drag" increases total aerodynamic drag by 10-15% hence increasing fuel consumption. The highest heat load that needs to be rejected by the engine determines the quantity of cooling air, resulting in systems that are over designed for typical driving. This research provides a strategy of adjusting the cooling airflow to match the engine requirements (via variable geometry intakes that can be under the control of the engine management computer) offering substantial reductions in fuel consumption and emissions.Read moreRead less
PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. ....PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. Extensive 1D and 2D laboratory experimental programmes will be carried out. Models of unit processes that occur in infiltration systems will be defined/developed and built into a physically based model of an infiltration system. This model could be used for reliable design of stormwater drainage and harvesting systems, bringing major benefits to the people of drier and more populated areas of Australia.Read moreRead less
Using solar photocatalytic oxidation processes to treat organic pollutants in wastewater. The proposal is to use physical-chemical and solar engineering approaches to increase the efficiency of solar photons in the photocatalytic oxidation process applied to the detoxification of organic pollutants in wastewater. New photocatalyists and the effects of photocatalysts's superficial characteristics on the treatment perfomance will be studied. A specific structure for a solar collector for the proce ....Using solar photocatalytic oxidation processes to treat organic pollutants in wastewater. The proposal is to use physical-chemical and solar engineering approaches to increase the efficiency of solar photons in the photocatalytic oxidation process applied to the detoxification of organic pollutants in wastewater. New photocatalyists and the effects of photocatalysts's superficial characteristics on the treatment perfomance will be studied. A specific structure for a solar collector for the process will be developed. A more efficient way to use solar photons in the process and a better conceptual design of solar collector will be two main outcomes expected from the project.Read moreRead less
Catchment-scale and riparian zone stormwater retention: can it restore stream hydrology? This project will test whether or not stormwater retention systems dispersed throughout a catchment can restore pre-development streamflows in peri-urban streams. It will provide a new model for the design of stormwater drainage systems which both protect aquatic ecosystems and reduce the demand for imported water in cities.
