Some relations for bodies in a canal, with an application to wave-power absorption

Abstract

By the use of Green's theorem, relations are derived for the interaction of regular waves with a body in a canal. These relations are then applied to the problem of wave-power absorption by a body in a canal; this being taken as a model of an infinite row of wave-power absorbers. Two particular shapes of wave-power absorber are studied by use of thin-ship approximation. It is shown that the efficiency of power absorption by. a body in a canal may be much reduced when there is more than one travelling wave mode present in the canal.
