Magneto-convection
Convection is the transport of energy by bulk mass motions. Magnetic fields alter convection via the Lorentz force, while convection moves the fields via the curl(v×B) term in the induction equation. Recent ground-based and satellite telescopes have increased our knowledge of the solar magnetic fields on a wide range of spatial and temporal scales. Magneto-convection modelling has also greatly ...
متن کاملSolar Surface Magneto-Convection
Magneto-convection simulations on meso-granule and granule scales near the solar surface are used to study small scale dynamo activity, the emergence and disappearance of magnetic flux tubes, and the formation and evolution of micropores. From weak seed fields, convective motions produce highly intermittent magnetic fields in the intergranular lanes which collect over the boundaries of the unde...
متن کاملMagneto-inertial convection in rotating fluid spheres
The onset of convection in the form of magneto-inertial waves in a rotating fluid sphere permeated by a constant axial electric current is studied through a perturbation analysis. Explicit expressions for the dependence of the Rayleigh number on the azimuthal wavenumber are derived in the limit of high thermal diffusivity. Results for the cases of thermally infinitely conducting and of nearly t...
متن کاملRayleigh-bénard Convection: Dynamics and Structure in the Physical Space
The main objective of this article is part of a research program to link the dynamics of fluid flows with the structure of these fluid flows in physical space and the transitions of this structure. To demonstrate the main ideas, we study the two-dimensional Rayleigh-Bénard convection, which serves as a prototype problem. The analysis is based on two recently developed nonlinear theories: geomet...
متن کاملParallel computational magneto-fluid dynamics
In a Priority Program on Massively Parallel Computing, eight Dutch research groups (http://www.phys.uu.nl/~mpr/) cooperate since 1995 to develop new algorithms and software to simulate the non-linear dynamics of thermonuclear, geo-physical, and astrophysical plasmas. As one result of this collaboration, the general-purpose Versatile Advection Codemonstrated excellent scaling properties across a...
