Some cases of wave motion due to a submerged obstacle

摘要: 1. As far as I am aware, only one case of wave motion caused by a submerged obstacle has been worked out in any detail, namely the two-dimensional due to circular cylinder; for this case, Prof. Lamb given solution applicable when cylinder is small radius and at considerable depth. The method can be extended bodies different shape, my object paper work simplest three-dimensional sphere. problem have considered specially resistance body. In calculated considerations energy applied train regular waves. But moving sphere system more complicated, like well-known pattern point disturbance, similar methods are not so easily applied; therefore directly horizontal resultant fluid pressure on Before working analysis repeated, because it necessary carry approximation stage further than Lamb’s order verify that same obtained energy.
