Abstract:Numerical simulations and wind tunnel experiments were carried out to study airfoils and a wind-energy collecting structure (wind-lens) suitable for Straight Wing Vertical Axis Wind Turbines (SWVAWT). The aim of this study is to increase the output power coefficients of SWVAWT. The numerical method is a direct numerical simulation (DNS) based on the finite difference method. The results of DNS revealed that symmetry airfoils are better than asymmetry airfoils for the output performance. In the wind tunnel expe… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
