Abstract
Numerical simulations using a two-fluid Eulerian model were performed for two-dimensional axisymmetric jets from a circular 20 mm diameter nozzle. The particle size vary between 30 and 180 μm and the particle charge ranges from 0.1 to 1. The modulations of the flow structures and the turbulent characteristics of the gas flow due to the solid particles with different sizes and rates of particle loading are studied. The jet spread and the decay of the mean center line velocity are calculated for all sizes and particle loading rates considered in this study. Additions of solid particles in the gas flow significantly modulate the turbulence of the gas in the nozzle as well as the flow rates. Fine particles suppress turbulence, while coarse particles improve turbulence.
