Nonaxisymmetric instabilities in turbulent electromagnetic pumps
Paola Rodriguez Imazio, Christophe Gissinger
The stability of annular electromagnetic pumps (EMPs) is investigated through 3D direct numerical simulations. When induction effects dominate dissipative processes, linear inducti…
Instability in electromagnetically driven flows Part II
Paola Rodriguez Imazio, Christophe Gissinger
In a previous paper, we have reported numerical simulations of the MHD flow driven by a travelling magnetic field (TMF) in an annular channel, at low Reynolds number. It was shown…
Passive scalars: mixing, diffusion and intermittency in helical and non-helical rotating turbulence
P. Rodriguez Imazio, P. D. Mininni
We use direct numerical simulations to compute structure functions, scaling exponents, probability density functions and turbulent transport coefficients of passive scalars in turb…
Intermittency in Hall-magnetohydrodynamics with a strong guide field
P. Rodriguez Imazio, L. N. Martin, P. Dmitruk +1
We present a detailed study of intermittency in the velocity and magnetic field fluctuations of compressible Hall-magnetohydrodynamic turbulence with an external guide field. To so…
Effective diffusivity of passive scalars in rotating turbulence
P. Rodriguez Imazio, P. D. Mininni
We use direct numerical simulations to compute turbulent transport coefficients for passive scalars in turbulent rotating flows. Effective diffusion coefficients in the directions…
Cancellation exponents in helical and non-helical flows
Paola Rodriguez Imazio, Pablo Daniel Mininni
Helicity is a quadratic invariant of the Euler equation in three dimensions. As the energy, when present helicity cascades to smaller scales where it dissipates. However, the role…
