Exploring the turbulent velocity gradients at different scales from the perspective of the strain-rate eigenframe
Josin Tom, Maurizio Carbone, Andrew D Bragg
Expressing the evolution equations for the filtered velocity gradient tensor (FVGT) in the strain-rate eigenframe provides an insightful way to disentangle and understand various p…

Multiscale preferential sweeping of particles settling in turbulence
Josin Tom, Andrew D Bragg
In a seminal article, \citet[J. Fluid Mech., 174:441-465]{maxey87} presented a theoretical analysis showing that enhanced particle settling speeds in turbulence occur through the p…
