Abstract
The aim of the current study is to investigate the effect of negative overlap ratio (OR) on the performance of the Savonius rotor in terms of coefficient of drag (Cd), coefficient of torque (Ct) and coefficient of power (Cp) with straight edge extension on overlap region. The simulations were carried out for the negative overlap ratio ranging from 0 to 0.4 with flow velocity of 0.5 m/s and tip speed ratio (TSR) of 0.6. The numerical simulation was carried out in Ansys fluent with finite volume approach. SST K-ω turbulence model is used with velocity inlet and pressure outlet boundary conditions. The maximum coefficient of power of 0.0953 was obtain for zero overlap ratio.
