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 the faculty of Aerospace Engineering at TUDelft in the Netherlands. Since then he works at the Energy Research Center of the Netherlands ECN (now TNO Energy Transition) on the field of wind energy. His main expertise is aerodynamics (and related areas) on which he is active as researcher and coordinator of several large national and international projects. In 2012 he completed a PhD at TUDelft which was based on the experiences gained on the field of aerodynamic engineering methods since the start of his career. Since 2018 he also works as professor on Wind Energy at the University of Applied Sciences Hanze in Groningen, the Netherlands for 2 days/week. Peter Fuglsang is Head of Blades R&D in the Offshore Business Unit of Siemens Gamesa Renewable Energy. He graduated in 1994as 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 Blades R&D in the Siemens Gamesa Renewable Energy Offshore business unit having the full responsibility for design, prototyping, certification and validation of new blades and upgrades for Siemens Gamesa Offshore wind turbines.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 proof of convergence theorem for finite analytic method, developing fractional finite analytic method for numerical solution of Navier-Stokes equations, developing modified turbulence near wall model and then verified through simulation and testing for gas turbine blade film cooling. His work in aerospace and wind energy includes business jet external configuration design optimization, wind turbine blade airfoil design optimization for efficiency and roughness insensitivity, and various wind turbine blade optimization theory and application. Over the years, he has published more than 10 journal papers, many more conference papers and a few patents for wind turbines. He joined Vestas in 2009 as a principal engineer and led various projects involving wind turbine blade/airfoil aerodynamic design analysis. Currently he works at Goldwind Americas as chief scientist responsible for wind turbine blade technology R&D and new blade development. He is one of the Chinese National Aerodynamic experts, recognized by Chinese central government.
