Interactions between Ocean Surface Waves and Currents

Abstract

A mathematical model is developed to describe the interaction between random ocean surface waves and the wake produced by a surface ship. Calculations are presented for the mean square free surface displacement energy for the short wave length components of the wave field and Its modification due to refraction by the surface wake. It is demonstrated that a significant reduction of the short wavelength contribution to the surface energy can result from this interaction. A procedure to calculate the spectral composition of the free surface and the spatial realization of the free surface displacement is outlined. Free surface realizations will be presented in a forthcoming report. Keywords: Ocean models, Wave-current interaction, Refraction, Surface waves, Wave action, Wake, Wave kinematics, Random wave field, Spectral action density, Spatial realization, and Fluid mechanics.
