Radial flow of a viscous,incompressible, electrically conducting fluid between two stationary,porous discs in the presence of transverse magnetic field

The problem of incompressible, electrically conducting viscous laminar flow between two non-conducting coaxial discs is studied, in the presence of transverse magnetic field of uniform intensity, when there is constant injection or suction at the discs. The problem is interesting both mathematically and physically. The solution, for small suction or injection, has been obtained for highly viscous fluid. The velocity profiles have also been drawn graphically.
