Fluid Dynamics Simulations and Interactions

This paper describes a numerical method for calculating the two-dimensional hydrodynamic coefficients of one or two infinitely long, arbitrary cylinders forced to oscillate in or below the free water surface. The oscillation modes, amplitudes and phases of the cylinders may be different from one another. Finite water depth and a quay can be taken into account. Special consideration has been given to the radiation boundary conditions. The computer program developed has been tested in various two-dimensional boundary situations; it has produced results in good agreement with results obtained by other methods.
