On the generation of dispersive shock waves [PDF]
Physica D: Nonlinear Phenomena, 2016 We review various methods for the analysis of initial-value problems for integrable dispersive equations in the weak-dispersion or semiclassical regime. Some methods are sufficiently powerful to rigorously explain the generation of modulated wavetrains, so-called dispersive shock waves, as the result of shock formation in a limiting dispersionless ...

Optimum Design of Rotor on Mud Pulse Generator
Shiyou jixie, 2017 The continuous wave mud pulse generator has a high transmission rate, and the generated pressure wave signal quality is mainly determined by the signal amplitude and spectral characteristics, which are closely related to the rotor shape.In order to ...

IMPULSE WAVES GENERATED BY LANDSLIDES
Coastal Engineering Proceedings, 1970 A study programme has been initiated to investigate the impulse waves generated by landslides originating entirely above the water surface It may be seen that the characteristics of this wave depend mainly on the slide volume and the Froude number of the slide upon impact with the water The resulting wave goes through a transition period For the ...

On the Wind Generation of Water Waves [PDF]
Archive for Rational Mechanics and Analysis, 2016 In this work, we consider the mathematical theory of wind generated water waves. This entails determining the stability properties of the family of laminar flow solutions to the two-phase interface Euler equation. We present a rigorous derivation of the linearized evolution equations about an arbitrary steady solution, and, using this, we give a ...

The Generation of Long Waves in the Laboratory
Coastal Engineering 1980, 1980 It became evident in the experimental aspects of a recent study of the propagation of nonlinear long waves past a step and up a slope that it was important to be able to generate waves which were initially well defined. The investigation dealt with the reflection and transmission of tsunamis past the continental shelf-break, and as such, two simple ...
