This paper presents a method to analyze the viscous flow around marine
propellers using boundary-layer strip theory. A state-of-the-art two-
dimensional boundary-layer formulation is coupled to a state-of-the-ar
t perturbation potential panel method used in marine propeller flow an
alysis. The coupling procedure is applied along strips of the blade wh
ere two-dimensional boundary-layer flow is assumed. For this paper the
se strips were assumed to be constant radial strips of the blade. The
resulting method is applied to a conventional marine propeller and com
parisons to experiments are given. Results include the global quantiti
es of thrust, torque, and efficiency and the local strip quantities of
displacement thickness and section drag coefficient. The resulting co
mparisons, showing the applicability of the method to conventional mar
ine propellers, are quite good.
