This blade is spinning at an angular velocity of -2.22 rad/s with respect to the incoming wind (the blade is thus spinning clockwise like most real wind turbines). The upstream wind speed (or should we say the free stream velocity?) is 12 m/s (a typical rated wind speed for a turbine this size) (say something about it being turbulent?. This blade therefore has a tip speed ratio, which is the ratio of tip velocity to incoming wind, of 8 (also a typical value).
