WAVE FORCE ON AN INFINITELY LONG CIRCULAR CYLINDER IN AN OBLIQUE SEA

Analysis of an infinitely long circular cylinder fixed with its generators horizontal so that it is half-immersed, with its axis lying in the free surface of water. A regular train of water waves is incident on the cylinder from an arbitrary horizontal direction, and is partly reflected and partly transmitted under the cylinder. Study is concerned with the vertical component of the wave acting on the cylinder. It is assumed that the fluid is inviscid, that the fluid motion is irrotational, and that the depth of water is infinite. The equations of motion are linearized, and surface tension is neglected. Use of the fact that the required vertical force component can be inferred from the solution of a related problem, called the generalized heaving problem wherein a certain normal velocity is prescribed on the cylinder so that water waves which travel obliquely outwards are generated.
