DRAG-FREE FLOW OVER A SUBMERGED RANKINE BODY

Abstract

We prove the existence of a family of immersed obstacles which have zero wave resistance in the context of the two-dimensional Neumann-Kelvin problem. We first build a waveless potential by superposing a source and a sink in a uniform flow, for an appropriate choice of parameters. The obstacle is obtained by a combination of streamlines of the waveless potential. Numerical simulations show that the construction is valid for a large set of parameters.
