Abstract

Computer aided method of obtaining the analytical empiric formula in the polynomial form to determine the torque coefficient with the rotor similarity parameters such as the Reynolds number, the aspect ratio, the buckets overlap ratio and the tip speed ratio was created. Polynomial coefficients were derived from the solution of linear algebraic equations system built on the base of the least-square method. Initial amount of data was taken by digitizing the charts with the wind tunnel tests results obtained for Savonius rotors.
