Atomization, Spraying, and Nebulization

Abstract

An overview and current state-of-the-art of new developments in atomization, spraying and nebulization for the production of particulate materials are presented. The fundamental mechanisms of atomization physics, Newtonian and non-Newtonian atomization, primary and secondary breakups and disintegration of liquid jets and liquid sheets are briefly introduced, based on the up-to-date literature. The atomizers based on the energy input used to cause atomization are explained with their widely used application areas and their limitations. Spraying processes have a wide variety of industrial applications (automotive, aerospace, combustion, power, agriculture, food, metallurgy, environmental, and others) but in this book we focused only on the explanation of the spraying processes such as spray drying, thermal spraying and nebulization used in the production of particulate materials. Finally we provided a summary of the spray measurement techniques for the spray characterization and visualization.
