A General Method for Calculating Three-Dimensional Laminar and Turbulent Boundary Layers on Ship Hulls. I. Coordinate System, Numerical Method and Preliminary Results.

Abstract

This report describes the progress made during the past year towards the development of a general method for computing three-dimensional incompressible laminar and turbulent boundary layers on ship hulls. The method employs an implicit two-point finite-difference method and an algebraic eddy-viscosity formulation. During the past year the efforts concentrated on the choice of an appropriate coordinate system; the calculation of the geometric parameters of this coordinate system; the numerical solution of the governing equation of the orthogonal curvilinear system; and obtaining preliminary results for simple ship forms. Further studies are in progress and will be reported in a forthcoming report.
