Hydromagnetic Equilibrium Ii. Stability in the Variational Formulation.
In a few recent papers (Woltjer," 2 Chandrasekhar3) a beginning has been made with a variational formulation of the problems of hydromagnetic equilibrium. A similar approach was followed by Kruskal and Kulsrud4 who examined the static equilibrium in a toroid from the variational point of view, making largely use of topological arguments. It seems somewhat doubtful whether this approach can be g...
متن کاملHydromagnetic Turbulence
Recent progress in astrophysical hydromagnetic turbulence is being reviewed. The physical ideas behind the now widely accepted Goldreich–Sridhar model and its extension to compressible magnetohydrodynamic turbulence are introduced. Implications for cosmic ray diffusion and acceleration is being discussed. Dynamo-generated magnetic fields with and without helicity are contrasted against each oth...
متن کاملOn hydromagnetic oscillations in a rotating cavity
Time-dependent hydromagnetic phenomena in a rotating spherical cavity are investigated in the framework of an interior boundary-layer expansion. The interior problem is shown to contain waves whose frequencies are of order o, A o and A2u, where w is the rotation rate of the cavity and A2 = B2/4npu2R2 < 1 is the Alfven number. B is an imposed magnetic field, p the fluid density and R the radius ...
متن کاملHall Effects on Hydromagnetic Rotating Couette Flow
The hydromagnetic Couette flow of a viscous incompressible electrically conducting fluid bounded by two infinite parallel non-conducting plates in the presence of a uniform transverse magnetic field is studied on taking Hall currents into account. The relevant equations are solved analytically. The solution obtained shows that the inclusion of Hall currents gives some interesting results. It is...
