Chaotic magnetic field reversals in turbulent dynamos
Christophe Gissinger, Emmanuel Dormy, Stephan Fauve
We present direct numerical simulations of reversals of the magnetic field generated by swirling flows in a spherical domain. In agreement with a recent model, we observe that coup…
On the ill-posedness of the Prandtl equation
David Gerard-Varet, Emmanuel Dormy
The concern of this paper is the Cauchy problem for the Prandtl equation. This problem is known to be well-posed for analytic data, or for data with monotonicity properties. We pro…
Magnetostrophic MRI in the Earth's Outer Core
Ludovic Petitdemange, Emmanuel Dormy, Steven A. Balbus
We show that a simple, modified version of the Magnetorotational Instability (MRI) can develop in the outer liquid core of the Earth, in the presence of a background shear. It requ…
Direct numerical simulations of the galactic dynamo in the kinematic growing phase
Christophe Gissinger, Sebastien Fromang, Emmanuel Dormy
We present kinematic simulations of a galactic dynamo model based on the large scale differential rotation and the small scale helical fluctuations due to supernova explosions. We…
