Abstract
In this study, a 2D model as the horizontal cross-sections for HAWT of NREL phase VI is investigated to figure out the flickering of aerodynamic force with six different geometries by pressure-based Navier-Stokes solver and k-ω SST turbulence model. All six cases presented have zero yaw angle and zero pitch angle. Computational domain is divided as sliding mesh and stagnation domains to simulate the blade motion. In this article the dynamic response of tower interference is performed by lateral force, lift force, pressure coefficient and velocity contour by locations of the blade. The aerodynamic response is arranged in an overshoot function for the lift force coefficient of the airfoil to account for the aerodynamic coupling with the tower. This work present in this study gives an insight into rotor structure aerodynamic and aeroelastic interaction.
