Stability of second grade Rivlin- Ericksen magnetofluid flow between parallel planes in presence of a magnetic field

The stability equations for lineal flows between parallel planes of a second grade Rivlin-Ericksen magnetofluid are given. Some numerical results have been obtained for the case where the external magnetic field is parallel to the flow direction, and we have started calculations for the case where the external magnetic field is perpendicular to the planes.
