Turbulent Boundary Layer and Viscous Resistance of a Submarine at High Reynolds Number

Abstract

A limited amount of data about turbulent boundary layers, obtained on a full-scale submarine, is presented. Mean wall-shear stresses were measured at four hull locations with Preston tubes, and mean velocity profiles in the boundary layer were measured at one hull location with pitot tubes. These measurements were made over a range of Reynolds numbers from 11 to 300 million. The measured profile for boundary-layer velocity, both full-scale and model, are seen to agree well with the velocity-similarity laws, and the measurements of shear-stress distribution agree with a solution of the momentum equation for a body of revolution.
