Numerical investigations of a novel vertical axis wind turbine using Blade Element Theory-Vortex Filament Method (BET-VFM)

The aerodynamic performance of three different configurations of vertical axis wind turbines (VAWT), namely: (a) conventional Darrieus troposkein VAWT (based on turbines designed by Sandia National Laboratories), (b) novel 50% STS-VAWT (50% shifted-troposkein-shaped STS-VAWT), and (c) novel 100% STS-VAWT were investigated numerically. An in-house code, which combined the blade element theory (BET) and the vortex filament method (VFM), was used. The main purpose of this work was to develop an aerodynamic code to predict the perform
