Geared toward graduate students in engineering, this widely used monograph presents a two-part approach that focuses on both analytical techniques and practical applications. Newly updated by the author. 1969 edition.


This newly updated edition presents the basic techniques for analyzing one-dimensional two-phase flow and shows how they can be applied to a wide variety of practical problems.
Praised by the Journal of Fluid Mechanics for its "most useful compilation of experimental results," the text features much of author Graham B. Wallis's own work. The first section of the two-part treatment is concerned with analytical techniques. Part two is organized around particular phase combinations, flow regimes, and practical applications.  
For advanced undergraduates and graduate students in engineering as well as professional engineers.
