The Near-Field Disturbance Created by a Body in a Stratified Medium with a Free Surface

Abstract

The inviscid equations of motion for a slender body in a stratified fluid are formulated in a way which clearly illustrates the relation between the vorticity in the flow and the internal wave behavior. This formulation makes it clear that the problem admits a singular perturbation expansion of the solution if the density variation is small (large Vaisala length). Analytic solutions valid in the near field are obtained for the case of a finite-thickness constant thermocline. These solutions include both internal wave and gravity wave perturbations to the basic potential flow.
