Flow visualization in a particle laden jet flow
Abstract
The results of a flow visualization study of the behavior of an unconfined, steady, fully turbulent, two phase jet of diameter 12.7 mm at the exit with velocities up to 25 m/s and containing particles with a mass density of loading up to 5 percent are described. The significant result is the demonstration of fan spreading, whereby some of the particulates carried by the jet take paths outside of the expected envelope of an equivalent single-phase jet. Measurements of the path angles and a new theory to explain the reason for fan spreading is reported.
