Aerodynamic drag and lift characteristics of a newly developed elliptical-bladed savonius wind turbine rotor

Abstract

The elliptical-bladed rotor that has shown its potential to harness wind energy more efficiently is considered for the present numerical and experimental studies. In the present investigations, initially 2D unsteady simulations have been conducted for the elliptical, modified Bach, Benesh and semicircular profiles of the Savonius rotor. This is to check and corroborate the past research findings. The geometric parameters such as overlap ratio, number of rotor blades and effect of shaft are then
