PRESSURE DISTRIBUTION ON TOWED AND PROPELLED STREAMLINE BODIES OF REVOLUTION AT DEEP SUBMERGENCE.

Abstract

Measured and computed pressure distributions were obtained for a well-streamlined body of revolution (fineness ratio of ten to one), with and without a propeller, at deep submergence. Velocity distributions over the surface of the body with and without an added boundary-layer displacement-thickness are obtained from the velocity-potential function for a surface distribution of sources. Propeller-induced velocities in the near field ahead of a propeller are estimated from a uniform sink-disk representation and a single sink representation is used for large distances from the propeller. Propeller interference (Image effects are obtained from discrete singularities placed along the body axis. Within the field of propeller influence, differences occur in the theoretical and experimental pressure distributions. These discrepancies are discussed. (Author)
