THE SURGE MOTION OF A CIRCULAR CYLINDER CONTAINING A CONCENTRIC CYLINDRICAL HOLE IN FINITE DEPTH

This paper deals with hydrodynamic forces of a single semisubmerged circular cylinder containing a concentric cylindrical holes constrained to move in a water domain of finite depth. The fluid domain is divided into inner and outer regions. The Laplace equations governing velocity potentials for the three regions are solved by separation of variables and expressed in terms of eigenfunctions of the resulting equations which satisfy appropriate boundary conditions. Continuity of pressure and velocity potentials, pressures and forces are obtained. Numerical results are plotted for added mass and damping coefficients for different draft-to-depth and radius-to-depth values and for various wave amplitudes.
