Droplets are encountered in nature and a wide range of engineering applications such as spray combustion, spray drying, spray cooling, spray atomization, spray deposition, thermal spray, spray inhalation, aerosol spray, crop spray, paint spray, and many others. The related areas span automotive, aerospace, metallurgy, materials, medicine, food processing, agriculture, meteorology, and power generation.

It was these applications that stimulated the fundamental research and development of the technologies associated with discrete droplets. In recent years, strong research efforts have led to significant strides in theoretical and experimental studies of droplet processes. The dramatic improvements in computer technology and advanced computational and measurement techniques have enabled the direct numerical modeling and on-line, in-situ measurements of droplet properties. This has resulted in improved atomizer design and the optimization of atomization and spray processes. These advances have significantly improved our understanding of discrete droplet phenomena, making it desirable to review these results in a timely manner.

Science and Engineering of Droplets: Fundamentals and Applications is the first book to encompass the fundamental phenomena, principles, and processes of discrete droplets of both normal liquids and melts — an area of interest to a huge range of industrial enterprises. It begins with a systematic review of various processes and techniques, along with their applications and associations with material systems. This is followed by a description of the phenomena and principles in droplet processes.

Target Audience: Experienced researchers, scientists, and engineers who are concerned with processes involving discrete droplets, atomization, and the like.
