We use direct numerical simulation of the Navier-Stokes equations for a two-phase flow (water and air) to study the dynamics of the modulational instability of free surface waves and its contribution to the interaction between the ocean and atmosphere. If the steepness of the initial wave exceeds a threshold value, we observe wave-breaking events and the formation of large-scale dipole structur...

INTRODUCTION Serotonin seems to play a central role in tinnitus. The intensity dependence of auditory evoked potential (IDAP) is considered an index of central serotonergic activity in the auditory cortex. The higher the steepness of the N1/P2 component amplitude-stimulus function slope (N1/P2 ASF slope as calculated by IDAP), the lower the central serotonergic activity. Similarly, the N1 ampli...

A fully coupled numerical model is developed to study wave interactions with perforated elastic disks. The flow past the surface represented by a quadratic pressure discharge condition practical validity. nonlinear nature of drop results in dependency hydrodynamic responses on steepness.

A Lagrangian flow model is used to investigate highly nonlinear, dispersive waves generated by moving seabed deformation (MSD) of an otherwise horizontal seabed. Applications include free surface wave responses co-seismic displacements and novel bed-driven making systems in surfing competitions. This paper considers gravity viscous liquid, without restrictions on steepness, dispersion coefficie...

Freak waves are both extremely large and highly transient time. Such a wave may lead to damage of ships deaths. In this paper, describe the connection between freak essential factor, we use WAVEWATCH III model simulating “New Year Wave” in North Sea explore wave, with importing ECMWF re-analysis wind field. By way, successfully simulate formation random wave. Analysis shows steepness small dire...

Generation of wave break is a characteristic feature of cardiac fibrillation. In this study, we investigated how dynamic factors and fixed electrophysiological heterogeneity interact to promote wave break in simulated two-dimensional cardiac tissue, by using the Luo-Rudy (LR1) ventricular action potential model. The degree of dynamic instability of the action potential model was controlled by v...

This paper presents a numerical investigation on the harmonic structure of hydrodynamic forces fixed and simplified representative floating production, storage offloading (FPSO) vessel hull under dispersive phase-focused wave groups. The high-fidelity model utilizes two-phase flow solver in open-source toolbox OpenFOAM. A series cases were computed using model, where effects steepness, bow diam...

The apparent steepness of hills and stairs is overestimated in explicit perception. These overestimations are malleable in that when physiological resources are compromised, apparent steepness is further overestimated. An alternative explanation of these experimental findings attributes them to demand characteristics. This article tests the relationship between estimated steepness and naturally...

The secondary wave field associated with undular tidal bores (known as whelps) has been barely studied in field conditions: the wave field can be strongly non-hydrostatic, and the turbidity is generally high. In situ measurements based on pressure or acoustic signals can therefore be limited or inadequate. The intermittent nature of this process in the field and the complications encountered in...

Assessments on the configuration design of ocean wave energy converter are fundamental to obtaining optimum performance under different environmental scenarios. In this study, physical experimental test was conducted investigate suitable proposed Flap-Float Horizontal (FFH) device. A 1:20 scaled model investigated in laboratory tank subjected normal conditions. Several parameters, including arm...
