Very few investigation works on numerical modelling of wave interaction with permeable structures address the randomness of the incident waves. Most of the existing studies propose analytical models for prediction of the structure-induced transformation of Cited by: The results for dam-break wave impacting on a porous square prism and solitary wave interaction with a vertical porous structure are used to validate the proposed 3D SPH porous model. This is then followed by the simulation of wave interaction with a detached shore-parallel breakwater to demonstrate the capability of the new by: 8. It is proven to be a promising tool and able to provide reliable prediction on the wave-structure interaction in coastal engineering. Book. Full-text available permeable structures usually. The validated model is then applied to investigate wave interaction with a detached shore-parallel breakwater of two layer porous media. The predicted 3D flow field inside and outside the permeable breakwater is analyzed. The spatial distributions of wave-induced current induced by wave .
Wave interaction with permeable structures AN ABSTRACT OF THE THESIS OF Chung-Pan Lee for the degree of Doctor of Philosophy in Civil Engineering presented on Aug For long permeable structures (large |κ i w|) the only contribution to the mean setup is the dissipation of the incident wave and the reflected wave at the front of the permeable structure. Under this condition the mean surface elevation simplifies to () η ¯ = α R H 2 8 h cos ϕ R + Δ η ¯ + 1 4 h a 1 2 + 2 a 1 ϵ 2 n 1 − e 2 κ i x. The key innovations in the numerical wave flume that are necessary for simulation of wave interaction with permeable and impermeable coastal structures are a porous flow model, and wave boundary conditions for generation and absorption of the waves. Two practical test cases will illustrate the present possibilities and limitations of the code. A new coupling model of wave interaction with porous medium is established in which the wave field solver is based on the two dimensional Reynolds Averaged Navier-Stokes (RANS) equations with a kε closure. Incident waves, which could be linear waves, cnoidal waves or solitary waves, are produced by a piston-type wave maker in the computational domain and the free surface .

Ahmed () studied wave interaction with vertical slotted walls as a permeable breakwater, intended to minimize pollution, be environmentally friendly, reduce construction time, and be. 3D simulation of wave interaction with permeable structures Article (PDF Available) in Coastal Engineering Proceedings 1(32) February with Reads How we measure 'reads'. The interaction between oblique water waves and floating bridge in the presence of a vertical partial flexible permeable barrier is studied under the assumption of the linear water wave theory in finite water depth. The associated mathematical problem is handled for a solution using the least-squares approximation method.
