Numerical Simulation of Two-Phase Gas-Particle Jet in a Crossflow

Abstract

A particle trajectory model to simulate the mean trajectories, velocities, and densities of a particle-laden gas jet injected into a uniform cross free stream has been developed. Governing equations were derived by considering a balance between forces acting on an elementary control volume of the crossjet along the trajectories of the gas and particle phases. The effects of particle size, particle loading ratio, injection angle, and the carrier gas to free stream velocity ratio and the particle-to-carrier gas velocity ratio at the jet exit on the average characteristics were investigated in this study. The computational results of the mean particle trajectories are in good agreement with available experimental observation. The present method should be useful to predict the average properties of a two-phase gas-particle jet in a crossflow.
