A new system for wind turbines and their blades

Researchers at Rochester Institute of Technology are developing biodiesel from microalgae grown in wastewater. To ensure wind turbines that are big in size work in a better manner, a new kind of air-flow technology may soon be introduced. Apart from other aspects, it will focus on efficiency of blades used in the wind turbines. The technology will help in increasing the efficiency of these turbines under various wind conditions. This is a significant development in the area of renewable energy after new wind-turbine power generation capacity got added to new coal-fired power generation in 2008.
Testing new systems to optimize the efficiency of wind turbines and their blades
Syracuse University researchers Guannan Wang, Basman El Hadidi, Jakub Walczak, Mark Glauser and Hiroshi Higuchi are testing new intelligent-system based active control methods with the support from the U S Department of Energy through the University of Minnesota Wind Energy Consortium. They record data in an intelligent controller after getting a rough idea of the flow conditions over the blade surfaces from surface measurement. This helps them implement real-time actuation on the blades. In this way, not only the efficiency of wind turbine system is increased but the airflow can also be managed.
Advantages of new systems to optimize the efficiency of wind turbines and their blades
  • They reduce noise.
  • They reduce vibration.
New developments that are being worked out to make wind turbines and blades more efficient
  • The overall working scope of the wind turbine can be enlarged by using the flow control on the outboard side of the blade beyond the half radius. Attempts are being made to increase the rated output power without increasing the level of operating range.
  • An anechoic chamber is being set-up to measure and define the effects of flow control on the noise spectrum of the wind turbine.
  • To know the airfoil lift and drag characteristics with suitable flow control while exposed to large-scale flow unsteadiness, efforts are being made to characterize airfoil in an anechoic wind tunnel facility at Syracuse University.
  • Scientists are also trying to attain a greater efficiency by placing blades at various angles through wind tunnel tests of 2.5 megawatt turbine airfoil surfaces and computer simulations.
