Abstract

The hydrodynamic problem of a submerged spheroid in waves is analysed based on linearized potential theory. An analytic formulation is derived and demonstrated by considering the problem of a stationary spheroid in head or following seas. Tabulated numerical results are obtained for a spheroid whose major axis is six times the minor axis, submerged at a depth twice the minor axis. Figures for many other cases are also provided. It is suggested that the present method can be extended to the problem of oscillating bodies at forward speed.
