Magnetohydrodynamic flow in a vertical annular channel in presence of a uniform axial magnetic field

Abstract

we have discussed the flow of an electrically conducting fluid in a tall vertical closed annular channel under magnetic field along the decreasing direction of gravitational acceleration. The expression for nondimensional axial velocity and temperature are obtained and shown graphically for varying values of ratio of two radii. we have discussed flow of a viscous incompressible electrically conducting fluid in a tall vertical closed annular channel in the presence of uniform magnetic field in vertical direction.
