In this paper BEM& Glauert theory of momentum are investigated for the magnitude of axial induction factor, thrust coefficients and axisymmetric pressure distribution by Kinner. The axial induction factor characteristic is analyzed around the rotor bladein order to determine the extent of velocity gradient in the flow stream relative to free stream. The influence of yaw and wake skew angles on the power coefficient of turbine is analyzed in order to understand the axial induction factor, flow direction from tip of blades in the wake stream and when blade passes the tower. The lift and drag coefficients vary with tip speed ratios and angle of attack and enables to determine the behavior of axial and tangential induction factor observed at different blade locations. The axial induction factor is verified also according to theazimuthal averaged positions of the turbine rotor during the operation.Keywords
