Abstract
This chapter discusses the nature of non-Newtonian fluids that are commonly employed, followed by a look at the nature of the idealized porous media and the geometrical complexity of true porous media. Fluid and porous media interaction, such as adsorption, mechanical entrapment, and inaccessible pore volumes, have direct effect on the flow and are analyzed and quantified. The chapter studies microscopic and macroscopic views of the flow and presents the predictive models available for the study of the non-Newtonian fluid flow through porous media. This includes models based on hydraulic radius concept, friction factor/Reynolds number relationship, and empirical methods. Non-Newtonian fluid flow through porous media has become increasingly important in a wide range of disciplines and industrial segments. Catalytic polymerization process, the injection of polymer and surfactant solutions into petroleum reservoirs to enhance oil recovery, food processing, and fluid flow through riving tissues are examples of the vitality of understanding the non- Newtonian fluid flow through porous structures.
