One method and two results are contributed to the complete understanding about MHD laminar flow in annular channel with transverse magnetic field in this paper. In terms of the method, a computationally cheap semi-analytic algorithm is developed based on spectral method and perturbation expansion. By virtue of the fast computation, dense cases with almost continuous varying Hartmann number M , Reynolds number Re and cross-section ratio η are calculated to explore the flow patterns that are…

Magnetohydrodynamic secondary flows at high Hartmann numbers
Laminar flows in annular ducts of rectangular cross-section subjected to a constant axial magnetic field B0 are considered. The equations of flow are treated by a perturbation method involving
Instabilities and turbulence in magnetohydrodynamic flow in a toroidal duct prior to transition in Hartmann layers
Abstract Flow of an electrically conducting fluid in a toroidal duct of square cross-section is analysed. The flow is driven by the azimuthal Lorentz force resulting from the interaction between the
Experimental and numerical study of electrically driven magnetohydrodynamic flow in a modified cylindrical annulus. I. Base flow
Shear layers in confined liquid metal magnetohydrodynamic (MHD) flow play an important role in geo- and astrophysical bodies as well as in engineering applications. We present an experimental and
Instability of magnetohydrodynamic flow in an annular channel at high Hartmann number
Instability of a flow of an electrically conducting fluid in an annular channel is analyzed. Strong constant magnetic field is imposed in the axial direction. Similarly to toroidal duct experiments,
An effective two-dimensional model for MHD flows with transverse magnetic field
This paper presents a model for quasi-two-dimensional MHD flows between two planes with small magnetic Reynolds number and constant transverse magnetic field orthogonal to the planes. A method is
MHD flow in an annular channel; theory and experiment
The theory of Hunt & Stewartson (1965) for MHD flow in a rectangular duct with conducting walls parallel and non-conducting walls perpendicular to the magnetic field is applied to the problem of
Magnetorotational instability in electrically driven flow of liquid metal : Spectral analysis of global modes
The spectral magnetohydrodynamics stability of liquid metal differentially rotating in transverse magnetic field is studied numerically by solving the eigenvalue problem with rigid-wall boundary
Inertial regimes in a curved electromagnetically forced flow
We investigated experimentally the flow driven by a Lorentz force induced by an axial magnetic field $\boldsymbol{B}$ and a radial electric current $I$ applied between two fixed concentric copper
