Unsteady MHD flow of a dusty conducting walter B-type fluid through a uniform pipe with sector of a circle as cross section in a magnetic field

Non-Newtonian fluids are of increasing importance in modern technology. Recently, considerable progress has been made in this field of study. The problem of unsteady magnetohydrodynamics (MHD) flow of n-immiscible visco-elastic fluids between two parallel and fixed non-conducting plates has been investigated. The visco-elastic fluids in different layers are all of Olydroyd type possessing different physical parameters. The velocities at the interfaces and skin frictions on the two bounding plates have been derived. A particular case for the fluids has been considered. Two special cases have also been considered here. (author). 10 refs
