Abstract:

A research program is underway at NRL to develop new methods for the numerical calculation of surface wave effects on marine structures. Sufficient progress has been made with one particular NRL-developed computer code, SPLISH, to demonstrate the attractiveness of numerical calculations for problems such as the wave flow over a submerged structure. A brief description is given in this report of the numerical method and of some recent computational results. The present results demonstrate that realistic time-varying local flow fields, pressures and forces on a near structure such as the half-cylinder on the ocean floor can be determined from numerical calculations for certain conditions. Comparisons between the numerical results from SPLISH and recent linear and fifth-order solutions for wave flow over a bottom seated half-cylinder show good agreement as do comparisons between the numerical results and experiments in a wave channel.
