Atomization and Sprays

The second edition of this long-time bestseller provides a framework for designing and understanding sprays for a wide array of engineering applications. The text contains correlations and design tools that can be easily understood and used in relating the design of atomizers to the resulting spray behavior. Written to be accessible to readers with a modest technical background, the emphasis is on application rather than in-depth theory. Numerous examples are provided to serve as starting points for using the information in the book. Overall, this is a thoroughly updated edition that still retains the practical focus and readability of the original work by Arthur Lefebvre.

Arthur H. Lefebvre (1923-2003) was Emeritus Professor at Purdue University. With industrial and academic experience spanning more than four decades, he wrote over 150 technical papers on both fundamental and practical aspects of atomization and combustion. The honors he received include the ASME Gas Turbine and ASME R. Tom Sawyer Awards, ASME George Westinghouse Gold Medal, and the IGTI Scholar Award. He was also the first recipient of the AIAA Propellants and Combustion Award. Vincent G. McDonell is Associate Director of the UCI Combustion Laboratory at the University of California, Irvine, where he also serves as an Adjunct Professor in the Mechanical and Aerospace Engineering department. Dr. McDonell, who received his PhD from the University of California, Irvine, also serves as Vice Chair for the Board of Directors at ILASS-Americas. He has done extensive research work in the areas of atomization and combustion, holds a patent in the area, and has authored or co-authored numerous papers in the field.
