... ABSTRACT The problem of non-linear radiated waves generated by a submerged circular cylinder undergoing a forced heaving oscillation is studied. The Linear Potential Flow (LPF) theory approximation is used as a reference to the solution. A Computational Fluid Dynamics (CFD) commercial software...

... days. A systematic processing of time series provided values of added-mass and drag coefficients for the different configurations, amplitudes and periods considered. Linear damping due to radiated waves was observed to be small. Hence the main source of damping was found to be quadratic damping...

... method to obtain the wave loads, without solving the diffraction problem itself for each wave direction, would be welcome. As a first attempt for beam waves only, this paper presents a very quick, simple and accurate method to obtain the wave loads from the potential coefficients and the radiated wave...

... that the amplitude of the body motion is small compared with a principal body dimension and the water depth is not small compared with a typical wavelength of the radiated waves, it is possible to apply Taylor series expansions to reduce the body surface and free surface boundary conditions of the full nonlinear...
