We study the propagation of low-frequency shallow water waves on a one-dimensional flow
of varying depth. When taking into account dispersive effects, the linear propagation of long …

The acoustic propagation in lined flow duct with purely reactive impedance at the wall is
considered. This reacting liner has the capability to reduce the speed of sound, and thus to …

There is not a general definition of a black hole. The intuitive idea is that a black hole
appears when there is a trap** region from which nothing can escape, bounded by an …

We consider dissipation of surface waves on fluids, with a view to its effects on analogue
gravity experiments. We begin by reviewing some general properties of wave dissipation …

We study the amplification of shallow-water waves in the course of their propagation in a
duct of a variable cross section with a spatially inhomogeneous flow. We derive the basic set …

Periodic spatial modulations arise in analogue gravity experiments aimed at detecting the
analogue version of the Hawking effect in a white-hole flow. Having the same spatial …

This work considers the propagation of sound in a waveguide with an impedance wall. In the
low frequency regime, the first effect of the impedance is to decrease the propagation speed …

In a moving acoustic medium, sound waves travel differently with and against the fluid flow.
This well-established acoustic effect is backed by the intuition that the fluid velocity bias …

In this letter, we propose an expression for the instantaneous acoustic radiation force acting
on a compressible sphere when it is immersed in a sound field with a wavelength much …

This thesis deals with chosen topics from the aeroacoustics of periodic structures. A critical
analysis of the application of the frequency-domain linearized Navier-Stokes equations on …
