Trapped air metamaterials for ultrasonic sub-wavelength imaging in water
Stefano Laureti, David A. Hutchins, Lorenzo Astolfi +8
Acoustic metamaterials constructed from conventional base materials can exhibit exotic phenomena such as negative refractive index, extraordinary transmission-absorption and sub-wa…
Transition between advection and inertial wave propagation in rotating turbulence
J. A. Brons, P. J. Thomas, A. Potherat
In turbulent flows subject to strong background rotation, the advective mechanisms of turbulence are superseded by the propagation of inertial waves, as the effects of rotation bec…
Coupling of Wideband Impulses Generated by Granular Chains into Liquids
S. Harput, S. Freear, P. Gelat +5
An ultrasonic transducer technology to generate wideband impulses using a one-dimensional chain of spheres was previously presented. The Hertzian contact between the spheres causes…
Mean flow anisotropy without waves in rotating turbulence
J. A. Brons, P. J. Thomas, A. Potherat
We tackle the question of how anisotropy in flows subject to background rotation favours structures elongated along the rotation axis, especially in turbulent flows. A new, wave-fr…
Uncertainty Quantification in Molecular Signals using Polynomial Chaos Expansion
Mahmoud Abbaszadeh, Giannis Moutsinas, Peter J. Thomas +1
Molecular signals are abundant in engineering and biological contexts, and undergo stochastic propagation in fluid dynamic channels. The received signal is sensitive to a variety o…
