A fully non-linear numerical wave tank (NWT), based on Computational Fluid Dynamics (CFD), provides a useful tool for the analysis of coastal and offshore engineering problems. To generate absorb free surface waves within NWT, variety maker (NWM) methodologies have been suggested in literature. Therefore, when setting up CFD-based user is faced with task selecting most appropriate NWM, which should be driven by rigorous assessment available methods. provide consistent framework quantitative...
The computational fluid dynamic (CFD) toolbox OpenFOAM is used to assess the applicability of Reynolds-averaged Navier–Stokes (RANS) solvers simulation oscillating wave surge converters (OWSC) in significant waves. Simulation these flap type devices requires solution equations motion and representation OWSC׳s a moving mesh. A new way simulate sea floor inside section mesh with dissipation zone presented. To accuracy solver, experiments are conducted regular irregular traces for full three...
Coastal boulder deposits (CBD), transported by waves at elevations above sea level and substantial distances inland, are markers for marine incursions. But whether they tsunami or storm can be difficult to determine. Equations from seminal work Nott (1997), here referred as the Approach, commonly employed calculate nominal wave heights masses, a means discriminate between emplacement mechanisms. Systematic review shows that this approach is based on assumptions not securely founded, direct...

The paper presents results from the Collaborative Computational Project in Wave Structure Interaction (CCP-WSI) Blind Test Series 2. Without prior access to physical data, participants, with numerical methods ranging low-fidelity linear models fully non-linear Navier–Stokes (NS) solvers, simulate interaction between focused wave events and two separate, taut-moored, floating structures: a hemispherical-bottomed cylinder moonpool. ‘blind’ predictions for heave, surge, pitch mooring load, are...
Oscillating wave surge converters are a promising technology to harvest ocean energy in the near shore region. Although research has been going on for many years, characteristics of action structure and especially phase relation between driving force quantities like velocity or surface elevation have not investigated detail. The main reason this is lack suitable methods. Experimental investigations using tank tests do give direct access overall hydrodynamic loads, only damping torque power...
During extreme sea states so called impact events can be observed on the wave energy converter Oyster. In small scale experimental tests these cause high frequency signals in measured load which decrease confidence data obtained. These loads depend structural dynamics of model. Amplification occur and is transferred through structure from point to cell located foundation. Since determination design cases for Wave Energy Converters originate experiments, this lack has a direct effect...
Abstract The vast majority of numerical wave tank applications are solved using finite volume-based, volume fluid methods. One popular modelling framework is OpenFOAM and its two phase solvers, interFoam interIsoFoam , enabling the simulation a broad range marine hydrodynamic phenomena. However, in many applications, certain aspects entire set possible phenomena not interest reduced complexity could allow use simpler, more computationally efficient solvers. barrier for application such...

Working on pulsed ultrasound principle, multi-frequency (1 to 14 MHz) allows velocity height...
Computational Fluid Dynamics (CFD) simulations, based on Reynolds-Averaged Navier–Stokes (RANS) models, are a useful tool for wide range of coastal and offshore applications, providing high fidelity representation the underlying hydrodynamic processes. Generating input waves in CFD simulation is performed by Numerical Wavemaker (NWM), with variety different NWM methods existing this task. While NWMs, impulse source methods, have been widely applied wave generation depth averaged, shallow...
This paper presents the first blind prediction stage of Tidal Turbine Benchmarking Project being conducted and funded by UK's EPSRC Supergen ORE Hub. In this stage, only steady flow conditions, at low elevated turbulence (3.1%) levels, were considered. Prior to a large laboratory scale experiment was in which highly instrumented 1.6m diameter tidal rotor towed through towing tank well-defined conditions with without an upstream grid. Details test campaign design released as part community...
The mathematical problem of establishing a collision probability distribution is often not trivial. shape and motion the animal as well device must be evaluated in four-dimensional space (3D over time). Earlier work on wind tidal turbines was limited to simplified two-dimensional representation, which cannot applied many new structures. We present numerical algorithm obtain such distributions using transient, three-dimensional simulations. method demonstrated sub-surface kite an example....
Wastewater regulation and treatment is still a major concern in planetary pollution management. Some pollutants, referred to as particulate matter, consist of very small particles just suspended the water. Various techniques are used for survey. Few them able provide real-time data. The development new, real time instruments needs confrontation with wastewater. Due its instability, modeling wastewater terms solids was explored. Knowing description wastewater, we tried produce synthetic...
Experimental testing of physical turbines, often at a smaller scale, is an essential tool for engineers to investigate fundamental design parameters such as power output and efficiency. Despite issues with scaling blockage which are caused by limitations in size flow velocity the test facilities, experimental tank laboratory environments perceived offering more control thus trustworthier results than field testing. This paper presents tests tidal turbine, performed using self-propelled barge...
This paper presents the first noise measurements of a quarter-scale subsea tidal kite (anchored to sea floor by tether and flying in figure-eight configuration water column) operating field conditions. Challenges measurement post-processing data are detailed. Results presented for three conditions kite: (1) varying turbine rotations per minute (RPM), (2) speed, (3) twisted tether. Turbine RPM was identified as main parameter influencing emissions.
