“…Bakhtyar et al [18] developed an Eulerian two-phase flow model to simulate the nearshore hydrodynamic processes driven by wave motion; the flow field was computed using the volume-of-fluid (VOF) method. The two-phase flow VOF model has been widely employed for tracking the free surface in simulations of wave breaking and wave interaction with coastal structures [13,19,20]. By using a VOF method similar to those that have been used in previous studies, Xie [21] investigated both spilling and plunging breakers, and obtained the velocity field of both the overturning jet and air entrainment.…”

“…In computational fluid dynamics (CFD) techniques, the porous structure effect has been considered in numerous ways. The modified Navier-Stokes equation including the resistance of the porous medium was defined as the governing equation, without directly modeling the porous structure [10,11]. Furthermore, the wave model and the seabedstructure dynamic model were combined; however, only a one-way coupling method has been used so far [12,13].…”

This study developed a two-dimensional fully nonlinear numerical wave tank (FN-NWT) to examine the nonlinear interaction between waves and dual submerged porous structures. Using the FN-NWT, not only reflection and transmission coefficients, but also wave deformation/force depending on porosity were investigated. The FN-NWT was developed using the boundary element method (BEM), and consisted of a fluid domain and a porous medium domain. Darcy’s law or the non-Darcy (Forchheimer) flow equation were applied to the flow passing through the porous domain. The wave reflection coefficient of the porous submerged structures agreed well with the given experimental data when using Forchheimer flow boundary conditions. Excessive attenuation of the transmitted wave occurred when Darcy’s condition was employed. The difference in each coefficient due to the spacing of the submerged structure was reduced in the porous structure compared with the non-porous structure. The difference according to the incident wave height was clearly revealed in the transmission coefficient. The developed dual-domain FN-NWT can be applied to investigate the nonlinear interaction between waves and porous structures as a first-cut design tool.

“…Also, the actual impact forces at the site are always less than that measured in laboratories (Cuomo et al) 5 . Hence, a realistic numerical simulation of waves in ANSYS Fluent is expected to predict the pressures reasonably well 6–8 . A seawall with rubcrete has not been analyzed until now, either numerically or experimentally.…”

Seawalls are structures built parallel to the shoreline as a reinforcement of a part of the coastal profile. Seawalls are generally subjected to impact loads due to wave impact. In order to withstand the impact loads, the concrete seawalls should possess sufficient impact resistance. The use of crumb rubber particles as a replacement of aggregates improves the energy absorption capacity of the concrete structure. The use of rubcrete in concrete seawalls has not been tried in the past. So, this paper presents the feasibility study of using rubcrete in the concrete seawall by assessing the toughness of rubcrete seawalls. The impact strength of seawall was assessed for rubcrete seawalls by replacing 5%, 10%, and 15% of fine aggregate by crumb rubber. Numerical wave simulation was carried out in ANSYS Fluent, and the wave was coupled to the structure by one‐way fluid–structure interaction. The results presented in the paper indicate that the addition of crumb rubber up to 15% shows enhanced toughness performance.
