Artificial Intelligence and Rubble-Mound Breakwater Stability
Breakwaters are coastal structures constructed to shelter a harbour basin from waves. There are two main types: rubble-mound breakwaters, consisting of various layers of stones or concrete pieces of different sizes (weights), making up a porous mound; and vertical breakwaters, impermeable and monolythic, habitually composed of concrete caissons. This article deals with rubble-mound breakwaters....
متن کاملTwin Plate Weir: A Flow Measuring Device (TECHNICAL NOTE)
For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...
متن کاملFlow Visualization Around a Non - Circular Tube
The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...
متن کاملRubble Mound Breakwater: Run-Up, Reflection and Overtopping by Numerical 3D Simulation
From the numerical point of view, the complexity of the fluid dynamic processes involved has so far hindered the direct application of Navier-Stokes equations within the armour blocks, due to the complex geometry and the presence of strongly non stationary flows, free boundaries and turbulence. In the present work the most recent CFD technology is used to provide a new and more reliable approac...
متن کاملAn Investigation on the Stability of Rubble Mound Breakwaters with Armour Layers of Antifer Cubes
This paper presents the results of hydraulic model tests on the stability of rubble mound breakwaters with armour layers of antifer cubes. The tests were performed using irregular waves. The effect of wave parameters and the structure slope on the stability of these artificial armour units has been investigated and the stability formulae have been derived. Finally a comparison between these for...
