Sidewall effects on the onset of interfacial Holmboe waves in stratified exchange flows at high Schmidt number
Guilherme Siqueira de Aquino, Metten M. de Lange, Adrien Lefauve +1
Predicting the onset of interfacial instabilities is central to understanding turbulent mixing in natural and engineered stratified shear flows. Here, we study the onset of travell…
Early onset of secondary shear instability in Kelvin-Helmholtz braids at high Reynolds number
Emma R. Bouckley, Sam F. Lewin, Adrien Lefauve
We study the onset of two-dimensional secondary shear instability (SSI) in the braid regions connecting primary Kelvin-Helmholtz billows in stratified shear flows. While strain ind…
Transition to the ultimate regime of turbulent convection in stratified inclined duct flow
Rundong Zhou, Adrien Lefauve, Roberto Verzicco +1
The stratified inclined duct (SID) flow provides a canonical model for sustained, buoyancy-driven exchange between two reservoirs of different density, and emerges as a new paradig…
Routes to stratified turbulence and temporal intermittency revealed by a cluster-based network model of experimental data
Adrien Lefauve, Yui Hin Marvil Cheung, Xianyang Jiang +1
Modelling fluid turbulence using a `skeleton' of coherent structures has traditionally progressed by focusing on a few canonical laboratory experiments such as pipe flow and Taylor…
