The Effect of a Propulsor on the Hull Boundary Layer of a Body of Revolution

Abstract

An axisymmetric boundary-layer prediction method has been modified to include an approximate representation of a lightly-loaded propulsor. It is shown that, given, the average increase in velocity at the propulsor position, the method is capable of predicting the effect of single and contra-rotating propellers on the boundary-layer flow in the vicinity of the propulsor. The propulsor effect is shown to be insignificant more than one propulsor diameter upstream.
