Enhanced dynamo growth in nonhomogeneous conducting fluids
Florence Marcotte, Basile Gallet, Francois Pétrélis +1
We address magnetic-field generation by dynamo action in systems with inhomogeneous electrical conductivity and magnetic permeability. More specifically, we first show that the Tay…
A Dynamic Film Model of the Pulsating Heat Pipe
Vadim Nikolayev
This article deals with the numerical modeling of the pulsating heat pipe (PHP) and is based on the film evaporation/condensation model recently applied to the single-bubble PHP (D…
Inverse cascade suppression and shear layer formation in MHD turbulence subject to a guide field and misaligned rotation
Santiago J. Benavides, Keaton J. Burns, Basile Gallet +2
Astrophysical plasmas are often subject to both rotation and large-scale background magnetic fields. Individually, each is known to two-dimensionalize the flow in the perpendicular…
A model of interacting Navier-Stokes singularities
H. Faller, L. Fery, D. Geneste +1
We introduce a model of interacting singularities of Navier-Stokes, named pin\,cons. They follow a Hamiltonian dynamics, obtained by the condition that the velocity field around th…
Radiative heating achieves the ultimate regime of thermal convection
Simon Lepot, Sébastien Aumaître, Basile Gallet
The absorption of light or radiation drives turbulent convection inside stars, supernovae, frozen lakes and the Earth's mantle. In these contexts, the goal of laboratory and numeri…
