Assessing the Ship Motion Prediction Capabilities of the Open-Source Model NEMOH Against Field Observations
Tianshi Yu, Ziyue Wang, Filippo Nelli +3
Accurate ship motion prediction is critical for safe and efficient maritime operations, particularly in open ocean environments. This study evaluates the capability of NEMOH, an op…
A computational fluid dynamics model for the small-scale dynamics of wave, ice floe and interstitial grease ice interaction
Rutger Marquart, Alfred Bogaers, Sebastian Skatulla +4
The marginal ice zone is a highly dynamical region where sea ice and ocean waves interact. Large-scale sea ice models only compute domain-averaged responses. As the majority of the…
Fourier Amplitude Distribution and Intermittency in Mechanically Generated Surface Gravity Waves
Elmira Fadaeiazar, Justin Leontini, Miguel Onorato +3
We examine and discuss the spatial evolution of the statistical properties of mechanically generated surface gravity wave fields, initialised with unidirectional spectral energy di…
Ship resistance when operating in floating ice floes: a combined CFD&DEM approach
Luofeng Huang, Jukka Tuhkuri, Bojan Igrec +5
Whilst climate change is transforming the Arctic into a navigable ocean where small ice floes are floating on the sea surface, the effect of such ice conditions on ship performance…
Wave turbulence and intermittency in directional sea states
Elmira Fadaeiazar, Alberto Alberello, Miguel Onorato +4
The evolution of surface gravity waves is driven by nonlinear interactions that trigger an energy cascade similarly to the one observed in hydrodynamic turbulence. This process, kn…
Wind generated rogue waves in an annular wave flume
A. Toffoli, D. Proment, H. Salman +7
We investigate experimentally the statistical properties of a wind-generated wave field and the spontaneous formation of rogue waves in an annular flume. Unlike many experiments on…
Non-Gaussian properties of second-order wave orbital velocity
Alberto Alberello, Amin Chabchoub, Odin Gramstad +2
A stochastic second-order wave model is applied to assess the statistical properties of wave orbital velocity in random sea states below the water surface. Directional spreading ef…
A review of hydrodynamic investigations into arrays of ocean wave energy converters
S De Chowdhury, J. -R. Nader, A. Madrigal Sanchez +7
Theoretical, numerical and experimental studies on arrays of ocean wave energy converter are reviewed. The importance of extracting wave power via an array as opposed to individual…
Sea ice floes dissipate the energy of steep ocean waves
Alessandro Toffoli, Luke G. Bennetts, Michael H. Meylan +4
Wave attenuation by ice floes is an important parameter for modelling the Arctic Oceans. At present, attenuation coefficients are extracted from linear models as a function of the…
An experimental model of reflection and transmission of ocean waves by an ice floe
Alessandro Toffoli, Alberto Alberello, Luke G. Bennetts +3
An experimental model of reflection and transmission of ocean waves by an ice floe is presented. Evolution of mechanically-generated, regular waves is monitored in front and in the…
The excitation of rogue waves in a variable medium: an experimental study on the interaction of water waves and currents
A. Toffoli, T. Waseda, H. Houtani +4
We show experimentally that a stable wave propagating into a region characterized by an opposite current may become modulationaly unstable. Experiments have been performed in two i…
Triggering rogue waves in opposing currents
Miguel Onorato, Davide Proment, Alessandro Toffoli
We show that rogue waves can be triggered naturally when a stable wave train enters a region of an opposing current flow. We demonstrate that the maximum amplitude of the rogue wav…
