Handbook of Wind Energy Aerodynamics

Bernhard Stoevesandt is heading the department Aerodynamics CFD and Stochastic Dynamics at the Fraunhofer Institute of Wind Energy and Energy System Technologies based in Oldenburg. He studied physics at the University of Bremen (Dipl. Phys., 2000). Afterwards he worked as a freelancer in the field of x-ray lenses. In 2002 he joined the University of Oldenburg in the field of wind energy power forecasting. In 2004 he started his PhD at the university on turbulence in wind energy aerodynamics finishing in 2010. In 2011 he joined Fraunhofer to soon become the Head of the department.He has participated and continues to participate in the IEA Wind Task 29 and 31 projects focusing on wind fields and aerodynamics. A main interest of the work lies in the development of advanced techniques for aerodynamic and site simulations for wind turbines. The main developments have been in the field of numerical flow simulations for wind turbines. Gerard Schepers graduated in 1986 at Delft University of Technology, Aerospace Technology. He then joined the department of Wind Energy at the Energy Research Center of the Netherlands, ECN in Petten the Netherlands where he worked as researcher but also as coordinator of various national research projects, 7 joint European research projects and 4 joint mondial IEA research projects.Moreover he was Involved in various industry related projects and from December 2007-December 2009 he was part-time stationed at Suzlon Blade TechnologyHis specialisations are Rotor Aerodynamics, Windfarm Aerodynamics, Aero-elasticity, Aero-acoustics, Wind Tunnel Testing, Wind Turbine Blade Design, cost optimization. In 2012 he compiled his 25 years experience on aerodynamic engineering model into a PhD thesis which was successfully defended at TUDelft. He is also involved in various lecture series in Dutch and foreign universities and since 2012 he works part-time as professor wind energy at the University of Applied Sciences NHL, in Leeuwarden the Netherlands. He is author of more than 40 peer-reviewed scientific articles and more than 100 conference papers and technical reports and he was keynote speaker and chairman at almost all major wind energy conferences. Peter Fuglsang is Head of Blades in the Offshore Business Unit of Siemens Gamesa Renewable Energy. He graduated in 1994 as Mechanical Engineer from Aalborg University, Denmark. From 1994 to 2004 he worked at Risø National Lab as a researcher in the fields of wind turbine aerodynamics, aeroelasticity, aeroacoustics, numerical optimization, cost modelling, wind tunnel testing and wind turbine blade design. He has been the project manager of National and European collaborative research projects and involved in Consultancy in wind turbine blade design and wind tunnel testing, supervision of PhD students and teaching at the Technical University of Denmark. In 2004 he joined LM Wind Power A/S as Manager of the Aerodynamics Team doing wind turbine blade design, airfoil design, passive & active flow control being responsible for strategy and innovation in area. He was responsible for establishing the LM Wind tunnel. In 2011 he joined Siemens Wind Power A/S and currently works as the Head of Department for Blades in the Siemens Gamesa Renewable Energy business unit having the full responsibility for design, prototyping, certification and validation of new blades and upgrades for Siemens Gamesa wind turbines. He is a member of the board in DANSIS (Danish Society for Industrial Flow Mechanics) and he is an examiner in the Danish Engineering education system. He has been opponent for several PhD defenses and has more than 10 peer-reviewed articles, numerous conference presentations and papers as well as more than 20 granted patents. Yuping Sun graduated in 1994 with a Ph.D. from University of British Columbia, specializing in turbulent flow and heat transfer simulation and testing. His main achievements include pr
