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…
Prandtl number effects on extreme mixing events in forced stratified turbulence
Nicolaos Petropoulos, Miles M. P. Couchman, Ali Mashayek +2
Relatively strongly stratified turbulent flows tend to self-organise into a 'layered anisotropic stratified turbulence' (LAST) regime, characterised by relatively deep and well-mix…
Inertial enhancement of the polymer diffusive instability
Miles M. P. Couchman, Miguel Beneitez, Jacob Page +1
Beneitez et al. (Phys. Rev. Fluids, 8, L101901, 2023) have recently discovered a new linear "polymer diffusive instability" (PDI) in inertialess rectilinear viscoelastic shear flow…
Routes to stratified turbulence revealed by unsupervised classification of experimental data
Adrien Lefauve, Miles M. P. Couchman
Modeling fluid turbulence using a 'skeleton' of coherent structures has traditionally progressed by focusing on a few canonical experiments, such as pipe flow and Taylor-Couette fl…
Data-driven classification of sheared stratified turbulence from experimental shadowgraphs
Adrien Lefauve, Miles M. P. Couchman
We propose a dimensionality reduction and unsupervised clustering method for the automatic classification and reduced-order modeling of density-stratified turbulence in laboratory…
Mixing across stable density interfaces in forced stratified turbulence
Miles M. P. Couchman, Stephen M. de Bruyn Kops, Colm-cille P. Caulfield
Understanding how turbulence enhances irreversible scalar mixing in density-stratified fluids is a central problem in geophysical fluid dynamics. While isotropic overturning region…
