Towards smart blades for vertical axis wind turbines: different airfoil shapes and tip speed ratios
Abstract t/c and its chordwise position x t/c as well as the leading-edge radius index I c/2. The analysis is based on 630 high-fidelity transient 2D computational fluid dynamics (CFD) simulations previously validated with experiments. The results show that with increasing tip speed ratio the optimal maximum thickness decreases from 24 %c (percent of the airfoil chord length in metres) to 10 %c, its chordwise position shifts from 35 %c to 22.5 %c, while the corresponding leading-edge radius index remains at 4.5. The results show an average relative improvement of 0.46 and an average increase of nearly 0.06 in C P for all the values of tip speed ratio.
