The Structure of Turbulence and Other Motions Beneath an Air-Water Interface

Abstract

This is the final technical report for Grant N00014-91-J-1200, entitled 'The Structure of Turbulence and Other Motions Beneath an Air-Water- Interface.' The grant period was from 1 November 1990 through 31 January 1994. This research couples definitive physical experiments and numerical simulation experiments to study three-dimensional, unsteady, real-fluid flows beneath the air-water interface. The overall goals for the long term are to develop a complete understanding of the flow physics and a numerical simulation tool that allows accurate prediction of the motion from a specified set of initial and boundary conditions. This report covers the early period of the long term project. The numerical tool developed is for the simulation of free-surface flows through the solution of the time-dependent, incompressible, Navier-Stokes equations with non-linear dynamic and kinematic boundary conditions. It is being developed in three dimensions; the two-dimensional version is operational. The physical experiments have focused on developing-accurate maps of the flow fields under the waves with and without a surface piercing body.
