Magnetohydrodynamic channel flow and variational principles
This paper deals with magnetohydrodynamic channel flow problems. Attention is given to a variational principle where the boundary conditions are incorporated via a suitable functional which is stationary at the solution of the given problem; the trial functions used for the approximate solution need not satisfy any of the given boundary conditions.

Local existence and uniqueness for the non-resistive MHD equations in homogeneous Besov spaces
In the paper, we consider the Cauchy problem of the non-resistive MHD equations in homogeneous Besov spaces. We prove the local existence and uniqueness of the solution to the non-resistive MHD equations by using the iterative scheme and compactness ...

Global magnetofluidostatic fields (an unsolved PDE problem)
A satisfactory theory of the Global MagnetoFluidoStatic (GMFS) Fields, where symmetric and non‐symmetric configurations can be dealt with on the same footing, has not yet been developed. However the formulation of the Nowhere‐Force‐Free, Local‐Global MFS problem about a given smooth isobaric toroidal surface 𝒮0 (actually, a degenerate initial‐value ...

Nonlinear dynamo in a short Taylor-Couette setup
It is numerically demonstrated by means of a magnetohydrodynamics code that a short Taylor-Couette setup with a body force can sustain dynamo action. The magnetic threshold is comparable to what is usually obtained in spherical geometries.

Combined effect of free and forced convection on MHD flow in a rotating porous channel
This paper gives a steady linear theory of the combined effect of the free and forced convection in rotating hydromagnetic viscous fluid flows in a porous channel under the action of a uniform magnetic field. The flow is governed by the Grashof number G, the Hartmann number H, the Ekman number E, and the suction Reynolds number S. The solutions for the

In this paper, the existence and uniqueness of the global smooth solution to an initial‐boundary value problem of one‐dimensional magnetohydrodynamics (MHD)–Vlasov equations are proved for large initial data. This equation is a fluid‐particle system which consists of the compressible MHD equations for the fluid coupled with the Vlasov equation for the ...

Instability through porous medium of two viscous superposed conducting fluids
The stability of the plane interface separating two viscous superposed conducting fluids through porous medium is studied when the whole system is immersed in a uniform horizontal magnetic field. The stability analysis is carried out for two highly viscous fluids of equal kinematic viscosities, for mathematical simplicity.

Magnetohydrodynamic cross‐field boundary layer flow
The Blasius boundary layer on a flat plate in the presence of a constant ambient magnetic field is examined. A numerical integration of the MHD boundary layer equations from the leading edge is presented showing how the asymptotic solution described by Sears is approached.

Some geometric properties of magneto‐fluid flows
By employing an anholonomic description of the governing equations, certain geometric results are obtained for a class of non‐dissipative magnetofluid flows. The stream lines are geodesics on a normal congruence of the surfaces which are the Maxwellian surfaces.
