The interaction between the oscillation of them and fluid motion is of importance in many design cases. For those special cylindrical bodies, a new type of local disturbance source is presented in the paper, which, being distributed on the sectional contour of the cylinders together with the known wave source, can be used to estimate the three-dimensional hydrodynamic forces on those cylinders of arbitrary section oscillating in still waters. The solution method both for wave forces and radiation forces is also discussed.展开更多

The solutions give explicity the variation pattern of the transmitted waves and the characteristics of the reflected waves, including the wave profile, amplitude, phase shift and evolution. The effects of the gap between the body and the sea bottom on the transmission and reflection of those waves are also discussed.展开更多
