Paper No: OMAE2020-18438
... in a horizontally unbounded fluid domain. Then, analytical solutions for the present physical problem are developed using the method of multipole expansions combined with the shift of polar coordinate systems. The wave exciting forces on the cylinder as well as the added mass and radiation damping due...

... equation is done, using the weighted summation of the product of the beam modes. The accuracy of the frequencies is compared with those from FEA studies. The radiation pressure on the bottom side of the plate is included to reduce the frequencies by the added-mass effect. The plate is then subjected...

...-submersible are calculated for free vibration in air. The fundamental frequency was 1.9 Hz for the beam element model and 1.5 Hz for the shell element model. When weights corresponding to a submerged structure in operation mode are considered, including the effects of added mass, the fundamental frequency...

... Navier Stokes Equations (RANSE). The free surface is modelled by a Volume of Fluid (VOF) approach. The results in this paper show a good agreement between experimental results and numerical results of both methods for aircushion pressure variations, added mass, damping and wave elevations inside...
