An intrinsic feature of turbulent flows is an enhanced rate of mixing and kinetic energy dissipation due to the rapid generation of small-scale motions from large-scale excitation. The transfer of kinetic energy from large to small scales is commonly attributed to the stretching of vorticity by the strain rate, but strain self-amplification also plays a role. Previous treatments of this connection are phenomenological or inexact, or cannot distinguish the contribution of vorticity stretching…

On the role of vorticity stretching and strain self-amplification in the turbulence energy cascade
Abstract The tendency of turbulent flows to produce fine-scale motions from large-scale energy injection is often viewed as a scale-wise cascade of kinetic energy driven by vorticity stretching. This

Turbulence and heat transfer on a rotating, heated half soap bubble
Abstract We use direct numerical simulations to study the two-dimensional flow of a rotating, half soap bubble that is heated at its equator. The heating produces buoyancy and rotation generates
Temporal dynamics of the alignment of the turbulent stress and strain rate
Energy transfer between scales in the turbulent cascade requires geometric alignment between scale-dependent turbulent stresses and strain rates. However, each of these tensors evolves dynamically
A physics-inspired alternative to spatial filtering for large-eddy simulations of turbulent flows
Abstract Large-eddy simulations (LES) are widely used for computing high Reynolds number turbulent flows. Spatial filtering theory for LES is not without its shortcomings, including how to define
Lagrangian dynamics of the tensor diffusivity model for turbulent subfilter stresses
Large-eddy simulations (LES) are most often considered attempts to numerically approximate the solution to the filtered Navier-Stokes equations (Leonard 1974; Meneveau & Katz 2000; Sagaut 2006). LES

Viscous depletion of vorticity is an essential and well known property of turbulent flows, balancing, in the mean, the net vorticity production associated with the vortex stretching mechanism. In
