Numerical Simulation of Internal Waves in the Littoral Ocean
Abstract
Our long-term goal is to employ numerical simulation to generate accurate predictions of nonhydrostatic internal-tide events, such as large internal waves and solitons, in the littoral ocean. Our oceanographic-scale objective is to work collaboratively with oceanographers carrying out fieldscale experiments to quantify the significant wave events triggered by internal tides, including the nonhydrostatic formation of solitons and their evolution. Our laboratory-scale simulation objective is to quantify the effects of the breaking instability as well as to study the three dimensional mechanisms of the breaking. These results will inform our field-scale efforts. This objective has been achieved by carrying out laboratory-scale simulations of waves breaking on slopes and in zones where wave characteristics are focused and comparing them to experiments being done by others in our laboratory. Our numerical objective is to blend a proven field-scale code with large-eddy simulation [LES] and the modeling of domains with irregular boundaries. Our tool is LES in three dimensions and time. Our numerical analysis objectives include accurate representation of the flow near rough boundaries, creation of improved models for the sub-filter scale [i.e., unresolved] motions, and optimization of the computer code for multiprocessor computer systems.
