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…

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 s…

Spatio-temporal boundary dissipation measurement in Taylor-Couette flow using Diffusing-Wave Spectroscopy
Enzo Francisco, Vincent Bouillaut, Tong Wu +1
Diffusing-Wave Spectroscopy (DWS) allows for the direct measurement of the squared strain-rate tensor. When combined with commonly available high-speed cameras, we show that DWS gi…
