On Empirical Model of Aerodynamic Torque Acting on Savonius Rotor

An empirical model intended for describing the aerodynamic torque acting upon Savonius rotor is proposed. This model allows for parametric analysis of complex mechanical and electromechanical systems containing Savonius rotor using methods of the general mechanics and the theory of dynamical systems. The model is verified using wind tunnel experiments. As an example, a wheeled cart driven by Savonius rotor is considered. Numerical simulation of dynamics of such cart is performed.
