Abstract:

This report describes three phases of work towards improving and extending the three-dimensional ship boundary layer calculation method of von Kerczek 1982. The three items discussed in this report are 1 the method has been extended to deal with roughness of the ship hull 2 a viscous inviscid interaction scheme has been developed but not yet computationally implemented and 3 the computer implementation of the basic von Kerczek momentum integral method has been improved in several details. These are described in this report. Keywords include GHRGeneral Hydrodynamics Research, Turbulence, Boundary layers, Ships, Viscous drag, and 3-Dimensional.
