... ABSTRACT The effects of stepped slopes on impermeable submerged structures are presented in terms of wave energy dissipation. The influences of various stepped heights on structures are also compared with conventional breakwaters such as smooth and vertical submerged breakwaters. Various cases...

... excitation, the transient effect will arouse a larger peak value at the natural frequency, which requires a longer physical dissipation time to eliminate. Under random excitation, it will not only lead to the increase of energy at natural frequency, but also affect the energy distribution at each order...

... the influence of different swell percentages were analyzed. It is concluded that the nonlinear parameters and infragravity wave height are proportional to the swell percentages in shallow water. In terms of energy transfer, the wave energy dissipation of bimodal sea is mainly high frequency wind wave...

... ABSTRACT The effects of stepped slope on submerged breakwater are investigated for the efficiency of wave energy dissipation. This paper focuses on stepped submerged breakwater with different step sizes and crest widths, which are carried out on numerical simulation (OpenFOAM®). Regular waves...

... ABSTRACT Flat plate breakwater is widely studied for wave dissipation due to its good performance near the water surface and low cost in deep-water area. However, fixed flat plate suffers from low adaptability problem due to various incoming waves. This paper studies the wave dissipation...

In the present work, three schemes (Standard- WCSPH, δ -SPH and Riemann–SPH) are firstly considered to simulate the case of an oscillating drop, as a classical free-surface flow benchmark...

... protection. The SWAN (Simulating Waves Nearshore) model has achieved good simulating results on vegetation-induced wave dissipation in the condition of pure waves, while the effects of the tidal currents are ignored. A revised formula based on Hu Suzuki, Zitman, Uittewaal and Stive (2014) formulation...

... for wave dissipation. Results show that a double plate configuration is more effective in attenuating wave energy than a single floe, regardless side effects that may occur due to nonlinear fluid motion overwashing the plates. INTRODUCTION Arctic sea ice is retreating in response to climate change (e.g...

... ABSTRACT The comprehension of the energy balance between the wind input, dissipation is still partially empirical. In this context, new field observations are still revealing important information about the sea surface dynamics. Wave breaking is the main source of wave energy dissipation...

... breaking can be captured as shock or hydraulic jump without any criteria and energy dissipation models. The parallel method of Message Passing Interface (MPI) is used to get acceleration of the simulation. Then, this model was applied to simulate deep-water wave propagation with breaking, including...

... ABSTRACT In the context of linear potential flow, the effect of viscous dissipation is often modeled by sudden pressure change in proportion to the local flow velocity across a surface. This model leads to a hyper-singular integral equation for the pressure jump across the surface but the jump...

In general, the wave attenuation mechanism of the artificial reef can be summarized as follows: the reef causes more dissipation than reflection to attenuate the waves; the reef reflects more short waves than long waves; long waves are mainly...

The evolutions of the energy components are shown for the overall fluid domain and, successively, for two sub- regions of the fluid domain: the region in which the waves propagates in the wave flume and the region in which the fixed barge is located. The amount of energy dissipated in the latter...
