Effects of flow parameters on the performance of vertical axis swirling type Savonius wind turbine

Al-Faruk, A. and Sharifian, A. S. (2015) Effects of flow parameters on the performance of vertical axis swirling type Savonius wind turbine. International Journal of Automotive and Mechanical Engineering, 12 (July-December). pp. 2929-2943. ISSN 2229-8649


Wind tunnel experiments were carried out on a geometrically optimal swirling Savonius turbine by varying flow parameters to determine their effects on power and torque coefficients. The optimum geometrical configuration used in this experiment was adopted from an earlier study that features 0.20 blade overlap ratio, 195˚ blade arc angle, and 1.06 rotor aspect ratio of a 320 mm diameter rotor with closed top end plate. The parameters considered in this experimental are the hot air temperature, hot air mass flow rate, hot air inlet diameter of swirl chamber, and the free-stream wind velocity. The results indicate that higher hot air temperature and hot air mass flow rate promotes performance of the turbine while power coefficient reached maximum at a certain hot air inlet diameter. Tests on the optimum geometry at four wind velocities revealed that power coefficients are higher in higher wind velocities.
