Diffraction of Surface Waves by a Submerged Body in Motion

Abstract

Surface waves at the water surface are influenced locally by a submerged moving slender body. In addition to the Kelvin wave pattern which would be created by the moving body when travelling at uniform speed under smooth water, waves on the surface can be diffracted; this report is concerned with the diffraction effect. It is assumed that a linearized theory can be applied, and that using slender body theory, relative wave heights can be evaluated. For the coincident wave-body direction case, approximate expressions for the results are obtained for three particular ranges of the encounter frequency and body velocity parameters.
