TL;DR: In this article, the authors developed a theoretical model of fluid flow for annular duct of two parallel plates or circular duct and study of Newtonian and non-Newtonian fluid flow by computational and numerical method.
Abstract: In last two decades research on the topic of synthesis, characterization and analysis of smart fluids like Magneto rheological (MR) and Electro rheological (ER) fluids is taking place. In this paper researchers working in experimentation, development of mathematical model by Bingham plastic model and Herschel-Bulkley method have been studied. MR/ER fluid have main advantage, that is its unique property, means Bingham plastic properties. The verification and validation of result of damping force and damping displacement depends on the application of an external magnetic field or no field. Developing the theoretical model of fluid flow for annular duct of two parallel plates or circular duct is done. And study of Newtonian and non Newtonian fluid flow by computational and numerical method.

TL;DR: This chapter discusses extension of Buckley–Leverett theory to analyzing immiscible flow of non-Newtonian fluids through porous media, and presents Buckley-Leverett type solutions for non- newtonian fluid flow in porous media.
Abstract: This chapter discusses extension of Buckley–Leverett theory to analyzing immiscible flow of non-Newtonian fluids through porous media. It presents Buckley–Leverett type solutions for non-Newtonian fluid flow in porous media. The first portion of this chapter is devoted to discussion of non-Newtonian fluids and rheological models, followed by governing equations for immiscible flow of non-Newtonian fluids. A Buckley–Leverett solution for displacement of Newtonian and non-Newtonian fluids is presented. Then, it analyzes displacement of a Newtonian fluid by a power-law fluid, a Bingham fluid by a Newtonian fluid, and non-Newtonian fluids in a radial system. A practical procedure is presented for calculating saturations for non-Newtonian fluid displacement. The analytical solutions and resulting procedure can be regarded as an extension of Buckley–Leverett theory to non-Newtonian displacement. For application, analytical solutions are used to verify numerical simulation results.
