The distribution of the disperse fraction of a polydisperse jet injected into a gas flow
Abstract
Analytical expressions describing the distribution of a polydisperse jet in a gas flow are obtained, and the cases of longitudinal and transverse aerosol injection are examined. The spray geometry and the droplet size distribution functions are used in sufficiently arbitrary form and are suitable for both direct-jet and centrifugal nozzles. The solutions employ relationships for the trajectories of individual droplets that have been obtained by using an empirical drag coefficient in a two-dimensional equation of motion. The resulting expressions for the disperse phase distribution over the flow cross section are reduced to a form convenient for engineering applications. Illustrative examples are given.
