Parametric Study of a Microtab on a DU Airfoil
Authors: , , ,
Abstract: A parametric study for design and analysis of a microtab (MT) on an airfoil is presented. These flow control devices consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. Numerical simulations applied to this concept solve the governing Reynolds-averaged Navier-Stokes equations on structured mesh. The aim of the current study is to find the optimal position to increase airfoil aerodynamic performance, therefore a parametric study of a MT mounted on the pressure surface of an airfoil DU91W(2)250 has been carried out. This airfoil has been selected because it is typically used on multi megawatt wind turbines blades, such as the 5 MW wind turbine of the NREL. To that end, 2D computational simulations have been carried out at Re= 7.106. Procedure and best cases are presented.
