Numerical study of seabed response and liquefaction around a jacket support offshore wind turbine foundation under combined wave and current loading

Water Science and Engineering, 2022
The seabed instability induced by the transient liquefaction when exposed to wave-current may threaten the safety of offshore structures. In this study, the Reynolds-averaged Navier–Stokes (RANS) equations with the k–ε turbulence model were used to ...

Statistics of surface gravity wave turbulence in the space and time domains [PDF]

, 2010
We present experimental results on simultaneous space–time measurements for the gravity wave turbulence in a large laboratory flume. We compare these results with predictions of the weak turbulence theory (WTT) based on random waves, as well as with ...

Mooring Drag Effects in Interaction Problems of Waves and Moored Underwater Floating Structures

Journal of Marine Science and Engineering, 2020
In contrast to either considering structures with full degrees of freedom but with wave force on mooring lines neglected or with wave scattering and radiation neglected, in this paper, a new analytic solution is presented for wave interaction with moored

Ultrasonic Rayleigh wave enhancements from angled defects in aluminium [PDF]

, 2011
Non-linear enhancements of ultrasonic surface wave amplitude and frequency have been observed when an incident wave interacts with a surface defect.

Observed eddy-internal wave interactions in the Southern Ocean [PDF]

, 2020
The physical mechanisms that remove energy from the Southern Ocean’s vigorous mesoscale eddy field are not well understood. One proposed mechanism is direct energy transfer to the internal wave field in the ocean interior, via eddy-induced straining and ...

The nature of short-ranged correlations in nuclear systems

Physics Letters B, 2020
We apply ideas of the parquet-diagram and optimized Fermi-hypernetted chain methods to determine the short-range structure of the pair wave function in neutron matter and compare these with Bethe-Goldstone results and those of low-order variational ...

Probing the Boundary between Classical and Quantum Mechanics by Analyzing the Energy Dependence of Single-Electron Scattering Events at the Nanoscale

Nanomaterials, 2023
The relation between the energy-dependent particle and wave descriptions of electron–matter interactions on the nanoscale was analyzed by measuring the delocalization of an evanescent field from energy-filtered amplitude images of sample/vacuum ...

Simulations of Wave–Structure Interactions in Incompressible SPH Using Modified Dynamic Boundary Conditions

Journal of Marine Science and Engineering
The simulation of free-surface flows in hydraulic engineering presents several challenges due to the intrinsic complexity of modeling a fluid that continuously deforms and evolves over time.

Gravity wave turbulence in a laboratory flume [PDF]

, 2007
We present an experimental study of the statistics of surface gravity wave turbulence in a flume of a horizontal size 12×6  m. For a wide range of amplitudes the wave energy spectrum was found to scale as Eω∼ω-ν in a frequency range of up to one decade ...
