Optimal transient growth and transition to turbulence in the MHD pipe flow subject to a transverse magnetic field
Yelyzaveta Velizhanina, Bernard Knaepen
We consider the influence of a transverse magnetic field on the transient growth of perturbations in a liquid-metal circular pipe flow with an electrically insulating or conducting…
On the instability of the magnetohydrodynamic pipe flow subject to a transverse magnetic field
Yelyzaveta Velizhanina, Bernard Knaepen
The linear stability of a fully-developed liquid-metal MHD pipe flow subject to a transverse magnetic field is studied numerically. Because of the lack of axial symmetry in the mea…
Enhanced steady-state dissolution flux in reactive convective dissolution
V. Loodts, B. Knaepen, L. Rongy +1
Chemical reactions can accelerate, slow down or even be at the very origin of the development of dissolution-driven convection in partially miscible stratifications, when they impa…
Controlling the level of the ideal invariant fluxes for MHD turbulence using TURBO spectral solver
B. Teaca, C. C. Lalescu, B. Knaepen +1
The ideal invariants present in the formalism of magnetohydrodynamics (MHD), i.e. global quantities that are conserved in the absence of sources and dissipative effects, play an im…
The Effect of Coherent Structures on Stochastic Acceleration in MHD Turbulence
Kaspar Arzner, Bernard Knaepen, Daniele Carati +2
We investigate the influence of coherent structures on particle acceleration in the strongly turbulent solar corona. By randomizing the Fourier phases of a pseudo-spectral simulati…
Statistical Properties of Dissipative MHD Accelerators
Kaspar Arzner, Loukas Vlahos, Bernard Knaepen +1
We use exact orbit integration to investigate particle acceleration in a Gauss field proxy of magnetohydrodynamic (MHD) turbulence. Regions where the electric current exceeds a cri…
