Is vortex stretching the main cause of the turbulent energy cascade?
In three-dimensional turbulence there is on average a cascade of kinetic energy from the
largest to the smallest scales of the flow. While the dominant idea is that the cascade occurs …

Clustering of aerosol particles in isotropic turbulence
It has been recognized that particle inertia throws dense particles out of regions of high
vorticity and leads to an accumulation of particles in the straining-flow regions of a turbulent …
