Since the publication of the first edition, there have been significant advances in science and engineering applications of multiphase flows. This second edition reviews these advances while maintaining the same pedagogical approach. The book features a new chapter on the latest developments in carrier-phase turbulence, as well as an extended chapter on numerical modeling that includes new concepts in dense phase flow models. In a chapter on droplet-particle cloud equations, the text now covers the kinetic theory approach, which is commonly used for dense phase flows and incorporated in commercial codes. The exercises have been expanded, and a solution manual is now available-- Provided by publisher.
