Design and analysis of a vertical axis wind turbine

Recently, there has been a resurgence of interest in vertical axis wind turbines (VAWT) due to its advantages over the conventional horizontal axis wind turbines. More experimental and numerical simulations is needed for the understanding of VAWT operations, and the performance for different blad...
