Hydromagnetic laminar flow of a conducting fluid in an annulus in presence of a radial magnetic field

The MHD effects are studied on the laminar flow of a viscous, incompressible and conducting fluid in an annulus with arbitrary time-varying pressure gradient and arbitrary initial velocity in presence of a radial magnetic field. Using the finite Hankel transform, solutions for both the unsteady and steady flow under different prescribed pressure gradients were found. (author)
