The Symposium on "The Influence of Polymer Additives on Veloc ity and Temperature Fields" was proposed to the General Assem bly of the International Union of Theoretical and Applied Me chanics (IUTAM) by the "Gesellschaft fur Angewandte Mathematik und Mechanik" (GAMM). The Symposium was held under the auspices of IUTAM in association with the "Deutsche Rheologische Ge sellschaft" (DRG) with responsibility for the organization ly ing with B. Gampert (Universitat-GH-Essen). The main aim of this IUTAM Symposium was to consider the funda mental aspects of the phenomena that occur when small amounts of polymers are added to turbulent flows (turbulent drag re duction) and laminar porous media flows. In particular atten tion was devoted to - the influence of molecular parameters of the polymers and solution properties, especially the elongational viscosity, on turbulent flow and laminar porous media flow; the influence of polymers on the turbulence structure in polymer drag reduction

The present work delivers a versatile, accurate and reliable wind tunnel facility that is particularly developed to test different flow control techniques for drag reduction in precisely adjustable test conditions. Skin friction changes of 0.4% are resolved, which is comparable to the most accurate reported studies in liquids. this high accuracy is verified through a comprehensive uncertainty analysis. Subsequently, various passive and active flow control strategies are investigated.

The third edition of Bubbles, Drops, and Particles in Non-Newtonian Fluids provides comprehensive coverage of the scientific foundations and the latest advances in particle motion in non-Newtonian media. Thoroughly updating and expanding its best-selling predecessor, this edition addresses numerical and experimental developments in non-Newtonian particulate systems. It includes a new chapter on heat transfer in non-Newtonian fluids in the free and mixed convection regimes and thus covers forced convection regimes separately in this edition. Salient Features: Demonstrates how dynamic behavior of single particles can yield useful information for modeling transport processes in complex multiphase flows Addresses heat transfer in Generalized Newtonian Fluid (GNF), visco-plastic and visco-elastic fluids throughout the book and outlines potential strategies for heat transfer enhancement Provides a new detailed section on the effect of confinement on heat transfer from bluff-bodies in non-Newtonian fluids Written in a clear and concise manner, this book remains an excellent handbook and reference. It is essential reading for students and researchers interested in exploring particle motion in different types of non-Newtonian systems encountered in disciplines across engineering and the sciences.

With contributions by numerous experts

This laboratory handbook offers clear guidelines and tips for the practical everyday application of viscosimetry, as well as supplying a comprehensive companion for the interpretation of viscosimetric data from simple to complex polymer solutions.
