Interdisciplinary in approach, this reference book combines results obtained by Western, Russian, and Eastern European researchers which will familiarize readers with the problems of liquid atomization. The atomization of liquids is of great practical importance and is used in almost all industries, including metal, transportation, agriculture and forest, environmental protection, food, air conditioning, and water treatment, as well as conventional and nuclear power plants. In addition to the basics of atomization processes, this book shows how to calculate and design the atomizers and how to measure the macro- and microstructure parameters of atomized liquid. It covers the physical processes of atomization, main types of atomizers and their design, measurements of spray characteristics, experimental investigations of atomizers, and applications of atomizers. Among the liquids that are most commonly atomized are fuels and water. However, all types of liquids with different properties can be used, including liquid metals. Accordingly, topics cover atomizer design aspects and considerations for choosing which atomizer to use in various circumstances. Chapter authors have made this book versatile, to present a wide review of atomizer design, to help atomizer designers use computational methods and experimental data, and to present different measurement methods of both laboratory and industrial type.
