Abstract:

New fundamental analytical representations of the near-field potential flow that corresponds to a given flow at a surface bounding a potential-flow region are given for three classes of free-surface flows in deep water: diffraction-radiation of regular water waves by an offshore structure, steady ship waves, and time-harmonic ship waves (diffraction-radiation with forward speed). These near-field flow representations, called Rankine and Fourier-Kochin representations, define the flow in terms of distributions of Rankine singularities and Fourier-Kochin distributions of elementary waves over the boundary surface and its intersection with the mean free surface. The Rankine and Fourier-Kochin near-field flow representations involve only simple ordinary functions. These flow representations extend the previously given Fourier-Kochin representations of waves.

More about this publication?

• The Journal of Ship Research is a quarterly publication providing highly technical papers on applied research in hydrodynamics, propulsion, ship motions, structures, and vibrations. While the Journal requires that papers present the results of research that advances ship and ocean science and engineering, most contributions bear directly on other disciplines, such as civil and mechanical engineering, applied mathematics, and numerical analysis. High quality papers are contributed from the U.S., Canada and overseas, with representation from established authorities as well as new researchers.
