Optimization of a vertical axis wind turbine using FEA, multibody dynamics and wind tunnel testing

Abstract

Wind as a renewable energy source is not yet fully exploited despite the permanent availability of this source. Moreover, in countries where renewable energy regulations are still absent, big scale application is still non-applicable. In this context, a domestic vertical axis wind turbine is designed and tested. Design phases first included a series of wind tunnel tests in order to select the appropriate airfoil geometry and the optimum number of blades. Scaling was then applied in order to obtain a desired output power. Optimization of system performance and appropriate component selection were realized with the aid of a multi-body dynamics analysis tool and finite element analysis.
