Figure 2: Comparison of particle statistics obtained from LES ( ) to experimental data (◦ )
of Sommerfeld & Qiu [21] at different axial locations (x normalized by the reference annulus radius
R = 32mm): (a) mean axial velocity, (b) rms axial velocity, (c) mean radial velocity, (d) rms radial
velocity, (e) mean swirl velocity, (f) rms of swirl velocity, (g) mean diameter (microns), (h) rms
of particle diameter (microns).
