A note on steady and unsteady hydromagnetic flow in a rotating channel in the presence of inclined magnetic field

Abstract Steady and unsteady hydromagnetic flow of viscous incompressible electrically conducting fluid under the influence of constant and periodic pressure gradient in presence of inclined magnetic field has been discussed to study the effect of slowly rotating systems with low frequency of oscillation when the conductivity of the fluid is low and the applied magnetic field is weak. Analytic solution has been obtained exactly and the influence of different parameters for steady flow viz. M 2 (Hartmann number), K 2 (rotation parameter) and θ (angle of inclination of magnetic field with the positive direction of axis of rotation) on the induced magnetic field component has been examined numerically.
