Abstract: The transport of vorticity in viscoelastic Walters B? fluid in the presence of suspended magnetic particles in porous medium is considered. Equations governing the transport of vorticity in Walters B? viscoelastic fluid in the presence of suspended magnetic particles in porous medium are obtained from the equations of magnetic fluid flow proposed by Wagh and Jawandhia (1996). From these equations, it follows that the transport of solid vorticity ? r is coupled with the transport of fluid vorticity 1 ? r in porous medium. Further, it is found that due to thermo-kinetic process, fluid vorticity may exist in the absence of solid vorticity in porous medium, but when fluid vorticity is zero, then solid vorticity is necessarily zero. A two-dimensional case is also studied.
