An analysis of the hydrodynamic problem of linear forces acting on a submerged
sphere in an infinite water depth was investigated by Wang [9]. By employing a special
series solution, Wang solved the governing equation satisfied by the velocity potential.
Wu and Taylor [10, 11] considered a submerged spheroid and obtained analytical
solutions for the linear forces. An analysis of wave induced drift forces acting on
MATIUR RAHMAN
a submerged sphere in finite depth was presented by Wu et al. [12]. They used the
method of multipole expansions as demonstrated by Thorne [8] to determine the linear
velocity potential for a finite water depth. In a recent study, Bora [1] and Bora
et al. [2] used the multipole expansion method of Thorne to obtain the velocity potential
for the problem of a submerged sphere in finite water depth. In that work the
mathematical problem was split into two boundary value problems: a diffraction and
a radiation problem.
