A CFD Study on the Structural Response of a Sloping Top Caisson

Abstract

The paper discusses preliminary results of a CFD study on the structural response of a Sloping Top Breakwater subject to wave overtopping. The analysis showed that the transmitted wave field act to increase both the landward and the seaward forces and that the conventional design methods may be not adequate to guarantee an appropriate degree of safety to the structure. The study also confirmed the previous finding by Walkden et al. (2001), which noticed the existence of strong impulsive loadings on the inner face of the wall, due to violent overtopping events.

Study on Wave Overtopping Discharge Affected by Guiding Wall Angle of Wave Dragon Device Using FLOW-3D Software

“…Modern CFD applications include various branches of physical science that can rely on CFD applications including heat transfer, radiation, nuclear reaction, electromagnetic field, oceanography, vascular medicine, and so on. The general CFD experiments were focused on the field of fluid mechanics and included nonlinear waves, viscous effects, overtopping wave, green water effects, slamming loads, wave breakage, etc [31]. Through the use of several CFD software programmes, researchers have recently been gradually exploring wave hydraulic behaviours and structural design performance, mainly in the area of wave overtopping discharges.…”
