Hydromagnetic flow of reiner-rivlin fluid between two coaxial circular cylinders with porous walls

A study is made of the flow of Reiner-Rivlin fluid between two coaxial circular cylinders with porous walls in the presence of a uniform radial magnetic field when the inner cylinder rotates about its axis with a transient angular velocity and the outer one is at rest. It is shown that the velocity is unaffected by the cross-viscosity, but the pressure is affected by it. Numerical results are presented by means of tables
