Heat Transfer to Non-Newtonian Fluids. Fundamentals and Analytical Expressions

This book has been written with the idea of providing the fundamentals for those who are interested in the field of heat transfer to non-Newtonian uids. It is well recognized that non-Newtonian fluids are encountered in a number of transport processes and estimation of the heat transfer characteristics in the presence of these fl uids requires analysis of equations that are far more complex than those encountered for Newtonian fl uids. A deliberate effort has be made to demonstrate the methods of simplication of the complex equations and to put forth analytical expressions for the various heat transfer situations in as vivid manner as possible. The book covers a broad range of topics from forced, naturaland mixed convection without and with porous media. Laminaras well as turbulent flow heat transfer to non-Newtonian fluids have been treated and the criterion for transition from laminar toturbulent fl ow for natural convection has been established. The heat transfer characteristics of non-Newtonian fl uids from inelastic power-law fluids to viscoelastic second-order fluids and mildly elastic drag reducing fl uids are covered. This book can serve the needs of undergraduates, graduates and industry personnel from the fields of chemical engineering, material science and engineering, mechanical engineering and polymer engineering.
