Abstract
The lifting-line theory of a wing in an exponential shear flow proposed by the first author is applied to partial cavitation. The governing equation due to Chen et al with respect to velocity potential far down stream is solved and a general solution is utilized to obtain induced attack angle. A relation of lift force to effective attack angle is described by the Taylor series expansion in the vicinity of geometrical attack angle. From both induced attack angle and lift force, a lifting-line equation is derived, and effects of shear parameter, cavitation number and aspect ratio on the partially cavitating wing characteristics are clarified through some numerical calculations.
