Evolution of particle-laden jet flows - A theoretical and experimental study

Abstract

A combined experimental/analytical investigation is being conducted to study the interaction of particles and turbulent fluid flowfields under a wide range of test conditions.As a first step, the developing region of an unconfined axisymmetric turbulent jet with and without glass beads of 105 /*m diam (d} has been addressed for two mass loading ratios, LR = 0.2 and 1.0.A well-defined data set suitable for the validation of two-phase flow models was obtained by using a two-component phase Doppler technique.The theoretical calculations, based on a stochastic Lagrangian treatment along with a two-equation turbulence model for two-phase flows, yield reasonable and encouraging agreement with the measurements.
