Abstract
An integral method for the calculation of boundary layers on ship hulls is presented. The method, based on the momentum integral equations and the entrainment equation, can be used with an arbitary non-orthogonal coordinate system and allows for large crossflow angles. Either Coles' family of velocity profiles or power law profiles with Mager's crossflow assumption may be chosen to characterize the flow within the boundary layer. Comparison with experiment shows that the method performs well over the large portion of the hull where the boundary layer remains thin. Near the stern the momentum thickness is still well-predicted but the solutions suffer from the inability of the velocity profiles to predict reverse crossflow.
