Waves generated by collisions of solitary waves

Physical Review A, 1987
The small-amplitude, long-wavelength perturbation expansion of the water-wave equation has been extended to the fourth order of approximation for overtaking collisions of solitary waves. It is found that collisions of solitary waves generate, besides the dispersive wave train reported by us earlier [Q.-s. Zou and C.-H. Su, Phys. Fluids 20, 2113 (1986)],

Lambda Waves and Occipital Generators

Clinical EEG and Neuroscience, 2013
The objective of this study was to identify the relationship between lambda waves (LWs) and other occipital waveforms, in a retrospective analysis of electroencephalograms (EEGs) of clinic and hospitalized patients at a single center. The LWs were correlated with α rhythm, photic driving, and positive occipital sharp transients of sleep (POSTS).

Waves generated by an inclined‐plate wave generator

International Journal for Numerical Methods in Fluids, 1988
AbstractThis paper describes the characteristics of small‐amplitude waves generated by a sinusoidally oscillating, inclined paddle‐type wavemaker operating in a constant‐depth channel. Two‐dimensional, linearized potential flow is assumed. A semi‐analytical method, the boundary collocation method, is used to establish the relationship between wave ...

Scott Russell’s wave generator

Physics of Fluids, 2000
In this paper we study the dynamics of a system consisting of a heavy box sinking vertically into water. The classic configuration is due to Scott Russell who used the sinking box in 1844 to illustrate the formation of a solitary wave in a long rectangular tank.

The Generation of a Tollmien-Schlichting Wave by a Sound Wave

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1980
Abstract A spectral numerical method is used to study the two-dimensional unsteady flow over a flat plate in the presence of a plane sound wave propagating parallel to the flow. For s = ωx/U∞ > O(1), no observable interaction or energy interchange between the sound wave and the Tollmien-Schlichting wave is present.

Generation method of wash wave by wave generator in model basin

2012 Oceans, 2012
A generation method of wash wave by using multi-segmented wave generators in model basin is proposed. In this method, wave generators are controlled by the wave generation data consisting of wave elevation and surface lateral velocity of wash wave on the free surface. The wave generation data are prepared by the results of Navier-Stokes computation for

Generation of Radio Waves in Pulsars

Nature, 1970
Pulsars generate radio waves by an unknown process which gives the highest volume emissivity known in astrophysics. The radiation forms a beam the width and polarization of which are independent of frequency. This article assembles the observational facts which any theory of emission must explain.
