Energy transfer and conversion in Strongly Anisotropic Magnetohydrodynamic Turbulence
Damiano Capocci, Sean Oughton, Moritz Linkmann
In homogeneous magnetohydrodynamic (MHD) turbulence without a background magnetic field driven by mechanical forces, an exact decomposition of the energy fluxes (D. Capocci et al.,…
No need to stay positive: a practical approach to direct numerical simulations of elastic turbulence
Damiano Capocci, Moritz Linkmann, Alexander Morozov
Successfully performing direct numerical simulations of polymeric flows remains a major challenge in computational fluid mechanics. In addition to the velocity field, such simulati…
TURB-MHD: an open-access database of forced homogeneous magnetohydrodynamic turbulence
Damiano Capocci, Luca Biferale, Fabio Bonaccorso +1
We present TURB-MHD, a database formed by six datasets of three-dimensional incompressible homogeneous magnetohydrodynamic turbulence maintained by a large-scale random forcing wit…
Narwhals and their blessings: exact coherent structures of elastic turbulence in channel flows
Alexander Morozov, Martin Lellep, Damiano Capocci +1
Solutions of long, flexible polymer molecules are complex fluids that simultaneously exhibit fluid-like and solid-like behaviour. When subjected to external flows, dilute polymer s…
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…
