The Calculation of Potential Flow about Ship Hulls.

Abstract

This memorandum is the second of three which describe a series of computer programs for the calculation of the growth of a boundary layer on a ship hull. The first described computer programs for the numerical approximation of ship hulls using smoothing splines. This memorandum describes the calculation of the potential flow around the numerically approximated hulls. The third memorandum will describe the calculation of the boundary layer growth. The potential flow is calculated using a first-order panel method which yields the cartesian components of the flow vector at a number of control points on the hull. These discrete cartesian flow vectors are converted to contravariant velocity components and splined to yield a continuous representation of the potential flow over the hull. Zero Froude number is assumed. User guides are given for programs implementing the panel method and for a program which splines the calculated velocities. Keywords: Hydrodynamics; (Canada).
