Statistics of phase fluctuations of an acoustic wave propagating through a turbulent flow
Gaurav Prabhudesai, Stephane Perrard, Francois Petrelis +1
We investigate the statistics of phase fluctuations of an acoustic wave propagating through a turbulent flow in line of sight (LOS) configuration. Experiments are performed on a cl…
Patterns in transitional shear turbulence. Part 2: Emergence and optimal wavelength
S. Gomé, L. S. Tuckerman, D. Barkley
Low Reynolds number turbulence in wall-bounded shear flows \emph{en route} to laminar flow takes the form of oblique, spatially-intermittent turbulent structures. In plane Couette…
Patterns in transitional shear turbulence. Part 1. Energy transfer and mean-flow interaction
S. Gomé, L. S. Tuckerman, D. Barkley
Low Reynolds number turbulence in wall-bounded shear flows en route to laminar flow takes the form of spatially intermittent turbulent structures. In plane shear flows, these appea…
A platform for investigating Bell correlations in pilot-wave hydrodynamics
Konstantinos Papatryfonos, Louis Vervoort, André Nachbin +2
Since its discovery in 2005, the hydrodynamic pilot-wave system has provided a concrete macroscopic realization of wave-particle duality and concomitant classical analogs of a grow…
Dynamics of flexible filaments in oscillatory shear flows
Francesco Bonacci, Brato Chakrabarti, David Saintillan +2
The fluid-structure interactions between flexible fibers and viscous flows play an essential role in various biological phenomena, medical problems, and industrial processes. Of pa…
Liquid interface shaping and transport phenomena induced by spatially inhomogeneous vibrations
Benjamin Apffel, Christian Wilkinson, Emmanuel Fort
Vibrations can dynamically stabilize otherwise unstable liquid interfaces and produce new dynamic equilibria, called vibro-equilibria. Typically, the vibrations are homogeneous in…
