Abstract

This report is a continuation of an earlier study (Kumar13; and Narasimha 1986) on the lift and pitching moment experienced by an airfoil placed within a turbulent boundary layer. The mean velocity in the turbulent boundary layer is represented in this report by a composite profile including the wall and wake laws with a slope that vanishes at the edge of the boundary layer. Results with this composite profile agree qualitatively with those of the one-seventh power law; profile investigated earlier, the maximum difference quantitatively being 22% in the lift coefficient at a blade height of 0.66 boundary layer thickness 6, and 47% in the pitching moment at a blade height of 0.6 delta.
