초록
The water wave interactions on any three‐dimensional structure of arbitrary geometry can be calculated numerically through the use of source distribution or Green’s function techniques. However, such a method can be computationally expensive. In the present study, the water wave interactions in floating circular cylinder arrays were investigated numerically using the eigenfunction expansion method with the three‐dimensional potential theory to reduce the computational expense. The wave excitation force, added mass coefficient, radiation damping coefficient,and wave run‐up are presented with the water wave interactions in an array of 5 or 9 cylinders. The effects of the number of cylinders and the spacing between them are examined because the water wave interactions in floating circular cylinder arrays are significantly dependent upon these.
