Impact of alignments between fluctuating and mean density gradients on the scale-dependent energetics of stably stratified turbulence
Soumak Bhattacharjee, Stephen M. de Bruyn Kops, Andrew D. Bragg
Non-trivial alignments between vorticity and the strain-rate tensor play an important role in the evolution of velocity gradients and the energy cascade in isotropic turbulence. He…
Mechanism generating reverse buoyancy flux at the small scales of stably stratified turbulence
Soumak Bhattacharjee, Stephen M. de Bruyn Kops, Andrew D. Bragg
Previous studies have shown that at the small-scales of stably stratified turbulence, the scale-dependent buoyancy flux reverses sign, such that there is a conversion of turbulent…
Investigating the parametric dependence of the impact of two-way coupling on inertial particle settling in turbulence
Soumak Bhattacharjee, Josin Tom, Maurizio Carbone +1
Tom et al.\ (J.\ Fluid Mech.\ 947, A7, 2022) investigated the impact of two-way coupling (2WC) on particle settling in turbulence. For the limited parameter choices explored, it wa…
