ATTIA, Hazem A.. Unsteady MHD flow of a dusty non-Newtonian Bingham fluid through a circular pipe. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2006, vol.28, n.3, pp.264-268. ISSN 1678-5878.  http://dx.doi.org/10.1590/S1678-58782006000300003.

In this paper, the transient magnetohydrodynamic (MHD) flow of a dusty incompressible electrically conducting non-Newtonian Bingham fluid through a circular pipe is studied taking the Hall effect into consideration. A constant pressure gradient in the axial direction and an uniform magnetic field directed perpendicular to the flow direction are applied. The particle-phase is assumed to behave as a viscous fluid. A numerical solution is obtained for the governing nonlinear equations using finite differences.

Palavras-chave : Fluid mechanics; magneto-fluid mechanics; circular pipe flow; non-Newtonian fluid; Bingham fluid.
