Gravity wave damping of hydrostatic oscillations for a buoyant disk

  • F. W. G. Warren (a1)

A disk (i.e. a body whose maximum thickness is small compared with its lateral dimensions) floats with its central plane of symmetry upright. Its hydrostatic oscillations are lightly damped by the reaction of the gravity waves generated. A damping coefficient is obtained. It is shown that superimposed upon these oscillations is a small displacement which decays with the time t like t−4 or t−5.
