Intelligent Sampling of Extreme-Scale Turbulence Datasets for Accurate and Efficient Spatiotemporal Model Training
Wesley Brewer, Murali Meena Gopalakrishnan, Matthias Maiterth +12
With the end of Moore's law and Dennard scaling, efficient training increasingly requires rethinking data volume. Can we train better models with significantly less data via intell…
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…
Collective vibrations of confined levitating droplets
Stuart J. Thomson, Miles M. P. Couchman, John W. M. Bush
We report a new type of fluid-based driven dissipative oscillator system consisting of a lattice of millimetric fluid droplets bouncing on a vertically vibrating liquid bath and bo…
Capillary levelling of free-standing liquid nanofilms
Mark Ilton, Miles M. P. Couchman, Cedric Gerbelot +6
We report on the capillary-driven levelling of a topographical perturbation at the surface of a free-standing liquid nanofilm. The width of a stepped surface profile is found to ev…
Gapped and gapless short range ordered magnetic states with wavevectors in the pyrochlore magnet TbTiO
E. Kermarrec, D. D. Maharaj, J. Gaudet +9
Recent low temperature heat capacity (C) measurements on polycrystalline samples of the pyrochlore antiferromagnet TbTiO have shown a strong sensitivity…
