The design of a racing car needs several aerodynamic steps in order to achieve high performance. Each component has an interaction with the others and performance requires good match between them. front wing is undoubtedly one main components determine strong downstream components. Gurney Flap (GF) small appendix perpendicular pressure side at trailing edge that can dramatically improve In lite...

In the present studies, effects of Gurney flaps on aerodynamic characteristics a static airfoil and rotating vertical axis wind turbine are investigated by means numerical approaches. First, mesh time step studies conducted results validated with experimental data in good agreement. The solutions demonstrate that usage flap increases lift coefficient CL slight increase drag CD. Furthermore, mou...
Chen Liu, Haijun Xie, Jun Xu, Chen Jian*, Ren Dai 2 School of Energy and Power Engineering, University of Shanghai for Science and Technology 3 E-mail: [email protected] 4 Abstract: 5 The Gurney flap (GF) is a miniature lift-enhancement device and is usually mounted at the trailing 6 edge of an airfoil. The GF and has been successfully applied to isolated airfoils, multi-element 7 airf...
The present work aimed to investigate the aerodynamic characteristics of a pitching wind turbine airfoil with Gurney flap under turbulent inflow. Experiments were carried out for DTU-LN221 offshore different turbulence levels at Reynolds number 105 order magnitude by replacing grilles in tunnel. dynamic stall analyzed measuring surface pressure and near-wake flow field. results demonstrated tha...
