DEAKIN University engineering researchers have been inspired by nature to design a new generation of wind turbine blade that increases the production of electricity.<\/p>\n
Using the shape and function of a seagull\u2019s wing as a starting point, a team at Deakin\u2019s School of Engineering has designed a blade that improves the generating capacity of small-scale wind turbines by 10 to 15 per cent.<\/p>\n
Dr Jorg Schluter, a senior lecturer in mechanical engineering at Deakin\u2019s Waurn Ponds campus, said the new design could improve the options for green power generation in remote locations.<\/p>\n
\u201cIncreasing the capacity of these small-scale turbines makes them far more useful for reliable power generation, especially in rural and remote areas.<\/p>\n
\u201cSmall scale wind turbines can operate as single generating systems on buildings and small sites much like the traditional farmhouse windmill that pumps water.<\/p>\n
\u201cBut small-scale wind turbines have the added benefit of operating in collaboration with solar power systems during seasonal weather changes such as in winter when there is generally less sun but more wind.\u201d<\/p>\n
Dr Schluter said there had been significant research on wind turbines used in large scale wind farms but very little research into small scale turbines.<\/p>\n
\u201cBlades designed for large wind turbines usually don\u2019t have good aerodynamic efficiency when scaled down.<\/p>\n
\u201cWe saw the potential to improve the generating capacity of the small-scale turbines and looked to the sky for ideas to improve the blade design.<\/p>\n
\u201cNature has a way of finding impeccable solutions and I think many of us have stood at the shoreline at some point in our lives and marvelled at sea birds soaring in the breeze, mastering aerodynamics better than anything man-made.\u201d<\/p>\n
Masters student Arun Joseph Thomas decided to test the potential of a seagull\u2019s wing using novel simulation and analysis software.<\/p>\n
His research included analysis of wind data collected in the Geelong area and showed the new style of wind turbine would deliver up to 15 per cent more power than a conventional wind turbine.<\/p>\n
\u201cThe curvature of their wings has been optimised over millions of years to extract the most out of the air at these smaller scales,\u201d he said.<\/p>\n
\u201cThe integration of the airfoil shape of a seagull’s wing into the design of a turbine blade increases the generating capacity of the turbine and suggests there is greater commercial potential for these smallscale turbines.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
