CONCEPTS IN DESIGN OF COASTAL STRUCTURES

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Environmental Design of Low Crested Coastal Defence Structures

Computational wave dynamics for innovative design of coastal structures

For innovative designs of coastal structures, Numerical Wave Flumes (NWFs), which are solvers of Navier-Stokes equation for free-surface flows, are key tools. In this article, various methods and techniques for NWFs are overviewed. In the former half, key techniques of NWFs, namely the interface capturing (MAC, VOF, C-CUP) and significance of NWFs in comparison with the conventional wave models...

Advances in Ebg Design Concepts Based on Planar Fss Structures

This paper presents an overview of the various applications of planar Frequency Selective Surfaces (FSS) to the synthesis of Electromagnetic Bandgap (EBG) structures that act as metamaterials, such as Artificial Magnetic Conductors (AMCs). Over the past few years, many designs such as singleand dual-band AMC surfaces, tunable AMC surfaces, angularly stable AMC surfaces, ultra-thin EBG absorbers...

Simulation of Wave Propagation over Coastal Structures Using WCSPH Method

In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
