Bubbles, Drops, and Particles in Non-Newtonian Fluids, Second Edition continues to provide thorough coverage of the scientific foundations and the latest advances in particle motion in non-Newtonian media. The book demonstrates how dynamic behavior of single particles can yield useful information for modeling transport processes in complex multiphase flows.
Completely revised and expanded, this second edition covers macroscopic momentum and heat/mass transfer from a single rigid or fluid particle or ensembles of particles involving strong inter-particle interactions including packed beds, fluidized beds, and porous media with different types of non-Newtonian fluids. It reflects advances made since the publication of the previous, bestselling edition with new material on topics such as extensional flow; time-independent, time-dependent and visco-elastic fluids; free settling behavior of non-spherical particles; and particle motion in visco-elastic and visco-plastic fluids, boundary layer flows, flows in porous media, and falling object rheometry.
An excellent reference and handbook dealing with the technological aspects of non-Newtonian materials encountered in nature and in technology, this book highlights qualitative differences between the response of a Newtonian and non-Newtonian fluids in the complex flows encountered in processing applications.

"Chhabra has again successfully drawn on his extensive experience and vast knowledge of the literature to offer the readers an excellent, expanded and fully updated review of some of the most important research dealing with this subject . . . well written and exceptionally useful reference book that anyone interested in particle non-Newtonian systems should have."
– Jalel Azaiez, University of Calgary, in Canadian Journal of Chemical Engineering, April 2007, Vol. 85
"The comprehensiveness of this volume is staggering, and in this respect the author has provided a compendium not even approximately matched elsewhere. Even in this age of instant retrieval, it is impressive that one person could be aware of the range of work described by Professor Chhabra."
– William R. Schowalter, Department of Chemical Engineering, Princeton University, in AiChE Journal, 2008, Vol. 54, No. 11
