Computation of Water Waves.

Abstract

The report contains the numerical implementation of a theoretical algorithm that generalizes the Euler equations for irregular flows. The main features of the algorithm are described, and the relevant equations are summarized. The spatial region occupied by the fluid is then discretized, and the numerical quadrature of the theoretical algorithm's governing equations is effected. Computational results are given for the following hydrodynamic free-boundary problems: (a) the fall from rest of a liquid with a profoundly nonlinear initial free surface; (b) the motion from rest of a liquid whose initial free surface is only slightly removed from its equilibrium position, and (c) the collisions of streams of fluid with formation of a jet. A program listing is given in the appendix. (Author)
