ABSTRACT
The spray properties of importance include mean drop size, drop size distribution, radial and circumferential pattemation, droplet number density, cone angle, and penetration. The quality or fineness of an atomization process is usually described in terms of a mean drop size. Various definitions of mean drop size are available (see Chapter 3), of which the most widely used is the Sauter mean diameter, which represents the volume/surface ratio of the spray. This definition of mean drop size has special significance for heat and mass transfer applications, such as spray drying and the combustion of liquid fuel sprays.
