Covering the basics of liquid atomization, this book familiarizes readers with the physical processes of liquid atomization, the main types of atomizers and their design, measurements of spray characteristics, experimental investigations of atomizers, and application of atomizers. It demonstrates how to calculate and design atomizers and how to measure the macro- and microstructure parameters of atomized liquid. With a copious amount of numerical problems available for use as student tutorials, the book is suitable as a supplemental text for courses in mechanical, chemical, fuel, aeronautical, civil, and agricultural engineering.
