Hi i am currently doing my dissertation in which i am designing a vertical axis wind turbine design that is a modification of that of a savonius design. A major problem that i am having is being able to predict the torque value of torque for my design in order for me to then predict the efficiency. I calculated the torque initially using the equation Torque = power/ angular velocity but this then went on to give me a 100 percent efficiency value which obviously is wrong.(adsbygoogle = window.adsbygoogle || []).push({});

Any help would be fantastic thanks.
