The Excess Dissipation of Energy in a Turbulent Boundary-Layer and its Departure from Log-Normality
Benjamin Musci, Sebastien Aumaitre, Enzo Francisco +2
We investigate turbulent dissipation in a von Karman flow using PIV and Diffusing Wave Spectroscopy measurements to directly compare bulk and wall dynamics. While bulk dissipation…
Energy-Optimal Allocation of Storage in Transmission Grid Networks
Emile Emery, Sébastien Aumaître, Hervé Bercegol
The deployment of renewable energy technologies supposes the connection to the power grid of many new, distributed, and variable electricity production facilities. Among the invest…
Microscopic model for a granular solid-liquid-like phase transition
Sébastien Aumaître, Nicolas Mujica
Forced granular matter in confined geometries presents phase transitions and coexistence. Depending on the system and forcing parameters, liquid-vapor and liquid-solid co-existing…
Spatiotemporal statistics of the dissipation rate at the boundary of a turbulent flow using Diffusing-Wave Spectroscopy
Enzo Francisco, Julien Lambret, Sébastien Aumaître
We use Diffusing Wave Spectroscopy (DWS) to perform the first direct space- and time-resolved measurement of the dissipation rate~ at the boundary of a turbulent flow. We have…
Extreme events in a random set of nonlinear elastic bending waves
Murukesh Muralidhar, Antoine Naert, Sébastien Aumaître
The processes that generate rogue waves on the sea surface remain a mystery. Despite their different natures, the nonlinear bending waves generated in a thin elastic plate share so…
