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…
