Abstract

A numerical model is developed to clarify three-dimensional effects of the radial injection of carrier gas and particles on the thermo-fluid fields of the plasma jet with and without swirl. The plasma-particle two-way interactions are modelled by coupling a Lagrangian approach for particle behaviour with an Eulerian approach for plasma flow under dense loading. The effect of radial injection of the carrier gas on the flow and temperature fields of the plasma jet with and without swirl is clarified by numerical simulation. The deformations of the plasma jet thermo-fluid fields caused by dense particle loading with and without turbulent dispersion of the particles are presented. It is shown that the high mass flow rate of the carrier gas affects plasma jet fields strongly and particle turbulent dispersion can control the deformation of the plasma jet fields. The given swirl flow reduces the momentum and energy transfers between plasma and particles.
