| A source distribution method has been developed to solve the radiation problem for a two-dimensional arbitrary shape body which undergoes forced oscillation while laterally translating at a constant speed in or below the free surface.;The analysis is mainly concerned with the evaluation of hydrodynamic behavior of fluid due to an oscillating cylinder in uniform current.;The study also deals with the limiting cases, i.e., simple oscillation without translation and simple translation without oscillation, by giving an in-depth consideration to the hydrodynamic characteristics such as the free surface wave elevation, hydrodynamic pressure distribution and hydrodynamic forces.;The numerical results were compared with all the available experimental data and other analytical results. Generally good agreements were observed.;The Haskind's velocity potential for a steadily moving source of pulsating strength was further extended to a numerically calculable form. The behavior of the waves due to the source was thoroughly investigated in the near and far-field.;The most interesting speed effects are that the added mass and damping coefficients fluctuate as functions of frequency and geometry of the body, and that each of mode of motion induces three modes of hydrodynamic forces. |
