Short-crested wave interaction with a concentric porous cylindrical structure
نویسندگان
چکیده
6 In this paper, theoretical study is carried out to investigate the general 3D short-crested 7 wave interaction with a concentric two-cylinder system. The interior cylinder is imperme8 able and the exterior cylinder is thin in thickness and porous to protect the interior cylinder. 9 Both cylinders are surface-piercing and bottom mounted. Analytical solution is derived 10 based on the linear potential theory. The effects of the wide range wave parameters and 11 structure configuration including porosity of the exterior cylinder and the annular spacing 12 on the wave forces, surface elevations and the diffracted wave contours are examined. 13

The effect of short-crested wave phase on a concentric porous cylinder system in the wind blowing open sea
Cylindrical structures are widely employed in the offshore engineering. How to protect the structures in real sea environment is a vital issue for scientists and engineers. In this paper, the interaction of short-crested waves with a concentric surface-piercing two-cylinder system is studied based on linear wave theory using the scaled boundary finite-element method (SBFEM), a novel semi-analyt...
متن کاملSteep. Short-Crested Waves and Related Phenomena
Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...
متن کامل3-D Poro-Elastoplastic Model for Short-Crested Wave-Induced Pore Pressures in a Porous Seabed
In this paper, a three-dimensional poro-elastoplastic model for the short-crested wave-induced pore pressures in a porous seabed is presented. Unlike the previous models, both elasticity and plasticity of seafloor are considered in the present model. This study considers the effects of wave and soil characteristics on the pore pressures and was validated with the previous wave experiment data. ...
