Expressing turbulent kinetic energy as coarse-grained enstrophy or strain deformations
Damiano Capocci
In turbulent flows, the fluid element gets deformed by chaotic motion due to the formation of sharp velocity gradients. A direct connection between the element of fluid stresses an…

TURB-Hel: an open-access database of helically forced homogeneous and isotropic turbulence
Luca Biferale, Fabio Bonaccorso, Moritz Linkmann +1
We present TURB-Hel, a database formed by two datasets of incompressible homogeneous and isotropic turbulence, maintained in a statistically stationary state by fully helical forci…

Energy Flux Decomposition in Magnetohydrodynamic Turbulence
D. Capocci, P. Johnson, S. Oughton +2
In hydrodynamic (HD) turbulence an exact decomposition of the energy flux across scales has been derived that identifies the contributions associated with vortex stretching and str…
