... and cavity evolution, a special apparatus is designed which could conduct oblique water entry at arbitrary angles with a progressive wave. With an internal force sensor mounted inside the cylinder, the time history of impact force is recorded during the water entry. The cavity and splash induced...

...). The authors have shown that the model successfully simulates both linear and nonlinear standing waves and simple sloshing problems and is more effective and efficient than simple boundary element meth- ods for these problems. In this paper, we develop the VSM to generate nonlinear progressive waves...

... by progressive waves. The experimental results show that the buildup of pore-water pressure and the resulting liquefaction first starts at the nodal section and spreads towards the antinodal section. The number of waves to cause liquefaction at the nodal section appears to be equal to that experienced...

... ABSTRACT: This paper summarizes the results of an experimental study directed towards the validation of a mathematical model for the buildup of pore water pressure and resulting liquefaction of marine soils under progressive waves. Experiments were conducted under controlled conditions...

... and the progressive wave mode for positioncontrolled machines. At present, the operation of force-controlled machines is based upon an empirical calibration. In contrast, the approach shown herein facilitates the computation of a theoretical transfer function. In considering this approach, the influence...

... deformation of a wave profile and water particle trajectories leading to breaking. The nonlinear analytical solution is verified by reducing to the Lagrangian second-order solution of progressive waves in both the limit of deep water and of constant water. INTRODUCTION The motion of a fluid particle within...

... The present study is to investigate the mechanism of turbulent fluctuation between regular progressive wave and neutrally buoyant horizontal round jet experimentally. A Particle Image Velocimetry (PIV) technique was employed to measure the instantaneous velocity field of the turbulent jet under...

... ABSTRACT This paper summarizes the results of an experimental investigation of the complete sequence of soil behaviour exposed to a progressive wave. The soil was silt with d 50 = 0.060 mm. Two kinds of measurements were carried out: Pore-water pressure measurements (across the soil depth...

... ABSTRACT Breaking wave judgment with the vertical water pressure gradient IS discussed. The judgment of wave breaking of the progressive waves and the standing waves is carried out. Using the amount of energy loss due to hydraulic jump from the viewpoint of analysis, the wave energy loss due...

... a perturbation technique. The present solution derived for short-crested waves can be reduced to both standing waves and progressive waves (with zero and ninety degree of incident waves). Three variables for short-crested waves, the velocity potential (A, wave frequency (w) and wave profile (7) are derived...

... Ferrari's Formula. The dispersion relation implies two progressive waves, one is a shorter wave than the incident water wave in low frequencies and the other is a longer wave in high frequencies as well as a pontoon-type floating structure. Those two progressive waves suggest two kinds of refraction...

.... there are three kinds of waves acting below the plate: (i) an undamped progressive wave, (ii) a damped progressive wave, and (iii) evanescent wave modes. The undamped progressive wave is due the flexural vibration of the plate and the gravity effect on waves in the plate- covered region, which is called...

Early results with regard to the latter example, namely the buildup of pore pressure around a buried pipeline subject to a progressive wave, are encouraging...

First, the calculations are done by a one-equation model for the turbulent wave boundary layer induced by nonlinear progressive waves and the calculated profiles are compared with the experimental data of van Doom (1981). The validity of the model...
