PERFORMANCE OF A STATIONARY SAVONIUS ROTOR WITH CIRCULAR ARC BLADE PROFILE

Static torque and drag coefficients of a stationary Savonius rotor with circular arc blade profile havebeen investigated by measuring the pressure distribution on the blade surfaces for different rotor angles.Experiments have been performed at a Reynolds Number 1.8×105 with rotors having no overlap. Resultsindicate that static torque coefficients vary considerably with the rotor angle. DOI: http://dx.doi.org/10.3329/jme.v43i2.17830
