In addition to the simple injection types described in Section 22.12.1, FLUENT also provides more complex injection types for sprays. For most types of injections, you will need to provide the initial diameter, position, and velocity of the particles. For sprays, however, there are models available to predict the droplet size and velocity distributions. Models are also available for droplet breakup and collision, as well as a dynamically varying drag coefficient which accounts for variation in droplet shape. These models for realistic spray simulations are described in this section.
Information is organized into the following subsections:
