Abstract This paper presents a comprehensive experimental study on the effect of extreme waves LNG carrier. The carrier model was equipped with variety sensors to measure motions, green water height deck as well local and global loads. Experiments in transient wave packets provided general performance terms response amplitude operators were accompanied by tests regular two different steepness. ...

The evaluation and consideration of the mean flow in wave evolution equations are necessary for accurate prediction fluid particle trajectories under groups, with relevant implications several domains, from transport pollutants ocean to estimation energy momentum exchanges between waves at small scales circulation large scale. We derive an expression a finite water depth, which, contrast other ...

A theoretical investigation associated with obliquely propagating ion-acoustic shock waves (IASHWs) in a three-component magnetized plasma having inertialess non-extensive electrons, inertial warm positive and negative ions has been performed. Burgers equation is derived by employing the reductive perturbation method. Our model supports both structures under consideration of electrons. It found...

BACKGROUND Enhanced sympathetic activity facilitates complex ventricular arrhythmias and fibrillation. The restitution properties of action potential duration (APD) are important determinants of electrical stability in the myocardium. Steepening of the slope of APD restitution has been shown to promote wave break and ventricular fibrillation. The effect of adrenergic stimulation on APD restitut...

Scalar (density) and tensor (gravity-wave) perturbations provide the basis for the fundamental observable consequences of inflation, including CBR anisotropy and the fluctuations that seed structure formation. In general, these perturbations are nearly scale invariant (Harrison-Zel’dovich spectrum), though slight deviation from scale invariance (“tilt”) can have significant consequences for bot...

Abstract A series of experiments were conducted in a wind-wave tank facility Marseilles (France) to study the effects preexisting swell conditions (represented by long mechanically-generated waves) on growth with fetch. Both monochromatic and irregular (JONSWAP-type) wave different values steepness have been generated presence constant wind forcing, for several velocities. spectral analysis tem...

This paper examines the hydroelastic response of a monopile structure, supporting an offshore wind turbine. A new numerical simulation tool is presented, coupling nonlinear potential flow solver to structural model based on modal superposition. The hydrodynamic Weak-Scatterer (WS) approach and assumes small perturbations incident flow. finite element method (FEM) used compute parameters, which ...

Many populated, tropical coastlines fronted by fringing coral reefs are exposed to wave-driven marine flooding that is exacerbated sea-level rise. Most not alongshore uniform, but bisected shore-normal channels; however, little known about the influence of such channels on variations runup and adjacent coastline. We conducted a parametric study using numeric model XBeach demonstrates channel re...

The multi-chamber Oscillating Water Column (OWC) device has recently become more attractive due to its potential high efficiency. In this paper, the hydrodynamic performance of a single-, dual- and triple-chamber OWC-breakwater are investigated experimentally. first instance, quantitative comparisons implemented understand OWC-breakwaters. Specific attention been dedicated capture width ratio (...
