| Abstract | |
The dynamic stall features of a simplified vertical axis wind turbine (VAWT) configuration are analyzed. Wall-resolved large eddy simulations (LES) are performed for a NACA0018 airfoil operating as a single blade VAWT, and the operational parameters are set to tip speed ratio lambda = 3, Reynolds number Re = 50, 000 and Mach number M = 0.1. The numerical model is validated by performing a grid convergence study as well as an analysis of the airfoil spanwise domain. Results suggest that a computational domain with 40% of the airfoil chord in the spanwise direction is sufficient to capture the underlying flow dynamics when compared with span lengths of 10% and 80% of the chord. A good agreement with literature results is observed in terms of the main flow features for similar setups both in terms of integral quantities and the overall flow behavior. (AU) | |
