Water wave interaction with an array of bottom-mounted surface-piercing porous cylinders

Hydrodynamic interaction with an array of porous circular cylinders

“…Under the assumptions of potential flow and linear wave theory, a semi-analytical solution has been obtained by an eigenfunction expansion method based on Williams and Li, 2000. Analytical expressions have been developed for the wave motion in the three regions i.e.…”

“…Therefore, the present method on wave excitation force evaluation is quite useful to evaluate the wave forces acting on the array of impermeable truncated vertical circular cylinders. It was reported that the porous circular cylinder is significantly effective to reduce the hydrodynamic force and wave run-up on the cylinder compared to the impermeable cylinder (Williams and Li, 2000).

An array effect of wave energy farm buoys

“…Multiple bodies can be studied with the same theoretical and numerical methods that are applied to waveeffects on a single body (McIver and Evans, 1984;Simon, 1982;Mavrakos and McIver, 1997;Williams and Li, 2000). Typically, the analysis of two or three interacting bodies is a straightforward extension, but the analysis of very large configurations is fundamentally more difficult.…”

Water Wave Interaction by Dual Cylindrical Cylinders with Partial Porous Area

“…In case of porous cylinders, the wave motions in the exterior and all interior fluid regions are expressed by Williams and Li [11], [12]. Wang and Ren [13] were the earliest to study the wave interaction with a concentric surface piercing porous outer cylinder protecting an impermeable inner cylinder.…”

“…In the present study, the 3D numerical analysis method is developed with Eigenfunction expansion method which is expressed by Williams and Li [12], and Wang and Len [13]. The analysis method could be applied for the wave force evaluation to the array of dual cylindrical cylinders with partial porous area, which consist of an impermeable inner cylinder and a porous outer cylinder.…”
