Book Description
Five studies are presented in this publication: A comparison between the behaviour of polymer solutions and flow characteristics of linear elastico-viscous fluid models. The study shows that no linear model can predict consistently all the observed non-Newtonian phenomena of polymer solutions; Turbulent flow of dilute polymer solutions through an annulus. Experimental and theoretical results are presented; Measurements of the dynamic response of flowing polymer solutions with a vibrating torsional quartz crystal are presented. The dynamic elastico-viscous response is found to be independent of the flow characteristics and shear rates; Drag reduction in developing boundary layers by injection of polymer solutions. Reduction of local friction coefficients is of the order of 65 percent, however, energy losses in the injection region decrease the total drag reduction efficiency. Effect of the injection concentration and discharge, width of slot and mean stream velocity are found; Drag reduction and degradation tests of several polymer solutions are presented. (Author).

Book Description
Numerical Simulation of Non-Newtonian Flow focuses on the numerical simulation of non-Newtonian flow using finite difference and finite element techniques. Topics range from the basic equations governing non-Newtonian fluid mechanics to flow classification and finite element calculation of flow (generalized Newtonian flow and viscoelastic flow). An overview of finite difference and finite element methods is also presented. Comprised of 11 chapters, this volume begins with an introduction to non-Newtonian mechanics, paying particular attention to the rheometrical properties of non-Newtonian fluids as well as non-Newtonian flow in complex geometries. The role of non-Newtonian fluid mechanics is also considered. The discussion then turns to the basic equations governing non-Newtonian fluid mechanics, including Navier Stokes equations and rheological equations of state. The next chapter describes a flow classification in which the various flow problems are grouped under five main headings: flows dominated by shear viscosity, slow flows (slightly elastic liquids), small deformation flows, nearly-viscometric flows, and long-range memory effects in complex flows. The remainder of the book is devoted to numerical analysis of non-Newtonian fluids using finite difference and finite element techniques. This monograph will be of interest to students and practitioners of physics and mathematics.
