Surface Waves in Thin‐Walled Air‐Filled Cylinders in Water

Unstable Surface Waves in Running Water

We consider the stability of periodic gravity free-surface water waves traveling downstream at a constant speed over a shear flow of finite depth. In case the free surface is flat, a sharp criterion of linear instability is established for a general class of shear flows with inflection points and the maximal unstable wave number is found. Comparison to the rigid-wall setting testifies that free...

The Deterministic Generation of Extreme Surface Water Waves Based on Soliton on Finite Background in Laboratory

This paper aims to describe a deterministic generation of extreme waves in a typical towing tank. Such a generation involves an input signal to be provided at the wave maker in such a way that at a certain position in the wave tank, say at a position of a tested object, a large amplitude wave emerges. For the purpose, we consider a model called a spatial-NLS describing the spatial propagation o...

Time-Reversed Refocusing of Surface Water Waves

A time-reversal mirror is, roughly speaking, a device which is capable of receiving a signal in time, keeping it in memory and sending it back into the medium in the reversed direction of time. A brief mathematical review of the time-reversal theory is presented in the context of the linear shallow water equations. In particular an explicit expression is given for the refocused pulse in the sim...
