A Numerical Study of the Vertical Round Jets in Cross-flows

A numerical study of the vertical round jets in cross-flows using the standard k-epsilon turbulence model is presented. The computational jet trajectories agree well with experimental data and theoretical results. We have acquired the jet trajectories at different jet ratios and their unified expression, the unified expressions of the inner and outer boundaries of the jet influence domain on the symmetrical planes, the maximum widths of the influence domain of the tracing particles on horizontal plane, the site of the maximum densities on jet cross sections, the relations between deviation of the maximum densities' site from the jet central and jet ratio. The numerical analysis presents clearly flow structures in the shape of a horseshoe in the jet downstream.
