Wind energy is the fastest growing form of renewable energy. One of the many challenges wind energy faces in today’s competitive energy market is due to performance losses associated with atmospheric icing events that are commonly experienced by wind turbines in the Northern United States. It is therefore imperative to develop accurate prediction methods that determine the power losses due to atmospheric icing events. Representative icing conditions can be generated at the Penn State Adverse Environment Rotor Test Stand (AERTS). A technique has been developed where the actual ice shapes can be molded and preserved for subsequent wind-tunnel testing. In collaboration with NCAR and Xcel Energy, the Penn State team has performed scaled ice accretion experiments in the AERTS facility representative of spanwise flow conditions along a notional 1.5-MW wind turbine blade. Wind-tunnel measurements of lift and drag of various iced airfoil shapes were performed and used to estimate the total power losses due to turbine icing for selected atmospheric icing conditions. This seminar highlights the ice accretion experiments and wind-tunnel tests performed at Penn State and discusses some of the implications that the results suggest for predicting performance losses due to icing as well as alleviating the former by means of advanced turbine controls.
Peter M. Blasco - Peter is a 2nd-year M.S. student in Aerospace Engineering at Penn State where he also completed his B.S. in 2013. Peter’s thesis research focuses on wind turbine icing where he is conducting scaled ice accretion experiments and wind-tunnel tests. Furthermore, Peter is thinking of novel ways for advanced turbine controls that can mitigate the adverse effects associated with turbine icing. In his spare time, he likes to hike, camp, rock climb, snowboard, and do plenty of other outdoor activities. He also enjoys to design, build, and fly radio-controlled aircraft and rotorcraft.
Dr. Jose Palacios - Dr. Jose Palacios joined the faculty of Aerospace Engineering at Penn State University in August 2013. Jose received his bachelor, MS and PhD in Aerospace Engineering from the same department and school. He spent 5 years as a post-doctoral researcher at the Penn State Vertical Lift Research Center of Excellence (VLRCOE). During that time, his main research focus has been aircraft and wind turbine icing. Jose has developed testing capabilities to investigate icing physics and methods to prevent ice accretion. The construction of an Adverse Environment Rotor Test Stand (AERTS) and an upcoming Ice Crystal Wind Tunnel have helped secure funds for on-going research in the field of rotorcraft icing physics, engine icing, de-icing systems, and ice protective coatings.
Dr. Sven Schmitz - Dr. Sven Schmitz joined the faculty of Aerospace Engineering at Penn State University in 2010. He received a diploma degree in Aerospace Engineering from RWTH Aachen (Germany) in 2002 and a Ph.D. in Mechanical and Aeronautical Engineering from the University of California Davis in 2006. Sven spent four years as a post-doctoral researcher and project scientist at Davis before coming to Penn State. He is an expert in rotary wing aerodynamics with an emphasis on vortical flows. His growing research program embraces the areas of wind turbine aerodynamics and rotorcraft aeromechanics. Current activities include wind farm wake modeling, icing on wind turbines, rotor hub flows, and rotor active control.
