Transport of dry aerosols in turbulent jets

The present study stems from the current need for experimental data related to the transport of polydisperse, dry aerosols in a carrier gas jet. The size and velocity of particles laden in a turbulent jet are measured using a phase-Doppler anemometer. The tests entailed use of nearly spherical, polydisperse glass beads to seed an air jet at a high enough Reynolds number of roughly 36 X 10(3). The probability density functions of both particle size and velocity are presented at the mouth of the orifice and at an axial station downstream of the jet exit. The possible dependence of velocity on particle size is discussed.
