2007 - 2010 Prof Michael Negnevitsky, Dr Enamul Haque, Dr Ameen Gargoom, Osman Haruni (Masters student), Steffen Becker (PhD student), A/Prof Kashem Muttaqi, Dr Saad Sayeef, Nashad Mendis Funded by: Australian Research Council, Hydro Tasmania and University of Tasmania |
The main objective of this project was to offer structure approaches to infrastructure development for the operation of remote area power systems with wind-hydrogen renewable generation solutions. The key components of the model were a wind turbine, electrolyser, hydrogen tank, battery bank, dual-fuel combustion engine, full-scale converter system and loads. The principal source of energy was the wind turbine which generated maximum available power from the wind, and excess wind power was used to produce electrolytic hydrogen by an electrolyser. Hydrogen was stored and mixed with diesel in a duel-fuel compression engine to produce electricity when wind is not available. The project investigated a process where hydrogen-diesel duel fuel was used in a combustion engine for efficient and optimal operation of hybrid renewable energy systems. |

ARC Linkage Grant: Skin Friction Control Using Engineering and Biological Surface Coatings 2006 - 2010 Dr Jane Sargison, Jessica Andrewartha (PhD student), Kathryn Perkins (PhD student), Prof Greg Walker, Dr Alan Henderson, Assoc/Prof Paul Brandner, Prof Gustaaf Hallegraeff, Dr Jon Osborn Funded by Australian Research Council, Hydro Tasmania and University of Tasmania |
This multidisciplinary study of biofouling in hydropower conduits involved a team of engineers, plant scientists and spatial information scientists. Biofouling causes significant energy losses in hydropower schemes, as well as in the shipping industry. This project synthesised laboratory measurements to investigate the physics of flows over freshwater biofilms, studies of the environmental conditions favoured by the biofouling species present in the Tarraleah Power Scheme, evaluation of biofilm mitigation techniques, and the characterisation of the surface condition of biofilms using close-range photogrammetry. This project resulted in the award of two PhDs, to Jessica Andrewartha (Engineering, The Effect of Biofilms on Turbulent Boundary Layers and the Implications for Hydropower Canals) and Kathryn Perkins (Plant Science, Taxonomy, Ecophysiology and Mitigation of Fouling Diatoms in a Hydro Electric Canal at Tarraleah Tasmania) in August 2010 and multiple publications (see publications). |

Unsteady Effects in Large Scale Film Cooling Holes 2006 - 2010 Dr Jane Sargison, James Porter (PhD student), Dr Alan Henderson, Prof Greg Walker Funded by Rolls Royce and University of Tasmania |
This project examined the internal flow dynamics of a typical fan-shaped film cooling hole, as found in gas-turbine aero-engines. Cooling is required to maintain turbine components at acceptable temperatures to prevent failure as design turbine entry temperatures continue to rise in search of greater engine efficiency. A unique facility was designed and constructed to conduct large scale testing of film cooling hole geometries. This project resulted in the award of a PhD to James Porter (Engineering, Influence of Internal Flow Configuration on the Flow Field Within and Around a Fan-Shaped Film Cooling Hole) in December 2010 and multiple publications (see publications). Research outcomes included data that will be used by jet engine designers to ensure that recommended levels of cooling air is distributed over cooled engine components. |
