TURBULENT BOUNDARY LAYER AND VISCOUS RESISTANCE OF A SUBMARINE AT HIGH REYNOLDS NUMBER

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 19,100,000 to 205,000,000. The measured profile for boundary-layer velocity, both full-scale and model, agree well with the velocity-similarity laws, and the measurements of shear-stress distribution are in agreement with a solution of the momentum equation for a body of revolution.
