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.

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

Such carbon loss accounts for about 15 percent of the total carbon consumption in smelting, and its reduction will provide considerable economic benefit besides contributing to mitigation of greenhouse gas emission. In the present project the effect of coke calcination and composite baking temperatures on the relationship between anode microstructure and reactivity in oxygen as well as carbon dioxide will be investigated, and optimum process conditions determined for minimum reactive carbon loss during smelting.Read moreRead less
Optimising Fouling Control in Membrane Bioreactors. Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs.

Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs. The proposal aims to reduce the costs of fouling control by understanding the optimal conditions to remove these depositions and improve the design of MBR modules, operating conditions and shear delivery in the membrane system.Read moreRead less
