Book excerpt: Multiphase Flows with Droplets and Particles, Third Edition provides an organized, pedagogical study of multiphase flows with particles and droplets. The revision presents new information on particle interactions; particle collisions; thermophoresis and Brownian movement; computational techniques and codes; the treatment of irregularly-shaped particles. An entire chapter is devoted to the flow of nanoparticles and applications of nanofluids. Features: Discusses the modeling and analysis of nanoparticles. Covers all fundamental aspects of particle and droplet flows. Includes heat and mass transfer processes. Features new and updated sections throughout the text. Includes chapter exercises and a Solutions Manual for adopting instructors. Designed to complement a graduate course in multiphase flows, the book can also serve as a supplement in short courses for engineers or as a stand-alone reference for engineers and scientists who work in this area.
