From Savonius to Bronzinus: a comparison among vertical wind turbines

In this paper the authors propose a novel vertical wind turbine named Bronzinus and obtained by comparisons and optimisations of classical Savonius rotors. We redesigned some proposed Savonius turbines using CAD software and simulated the virtual behaviour of rotors using CFD software. A comparison among classical turbines and our Bronzinus underlines high Cp and Ct values of our proposed solution. This is a first step of a research oriented to design and develop new vertical wind turbines to solve energy problems in Lebanon. The research is proposed by an Italian company and an Italian University in collaboration with private Lebanese building Constructors. (C) 2014 Elsevier Ltd.
