RÉSUMÉ

Pulsatile flow of a viscous stratified fluid of variable viscosity between permeable beds is studied. The flow between permeable beds is governed by Navier-Stokes equations and the flow through permeable beds is governed by Darcy's law. The velocity field is obtained for steady and unsteady cases. The volume flux and fractional increase are also determined and the results are deduced and discussed through graphs.
