Book excerpt: For some time, remotely sensed data of the ocean surface have been used to determine surface conditions. It was clear that ship wake features could be readily identified in the remotely sensed data. The recent SIR/B series of synthetic aperture radar experiments were analyzed and clearly showed that surface vessels can be located by wake detection and that it may be possible to classify ship types by certain wake characteristics. As a result of these and other observations, the hydrodynamic characteristics of surface ship wakes have been of growing interest. A procedure for obtaining a set of near wake initial condition data for the parabolic numerical simulation of the turbulent far wake of a surface ship is developed. The principal elements of a surface ship wake are considered and are modeled based on experimental data. The wakes of the individual elements are assembled using linear superposition. Interactions among elements are discussed but not modelled. The superposition procedure is implemented in a computer code which uses parameters of the ship as program input. Results generated by the code for a guided missile destroyer model are presented and compared with limited experimental data. Keywords: Parabolic Navier-Stokes equations; Numerical simulations; Initial data plane.
