Couette Flow of a Bingham Fluid in a Channel Bounded By Permeable Beds with Suction and Injection

Viscous flow through and past porous media is of fundamental importance in various branches of Science and Technology. Fluid flows involving Porous media occurs in oil production, filtration, coalescence and in biological transport. The petroleum engineers are interested in seepage problems arising in extraction of petroleum from oil wells. The civil engineers and geologists are interested to know the ground water movement in porous layer in earth in order to tap water effectively and solve water scarcity problems in drought areas. The biologists are interested in water movement through plants which needs the knowledge of flow through porous media. Hence it is necessary to study flow through and past porous media. Some recent studies in this direction are given in references [19-25].
