Figure 4: Radial variations <strong>of</strong> droplet statistics at different axial locations (x normalized by the<br />
core radius R = 20mm) compared to experimental data <strong>of</strong> Sommerfeld & Qiu [22], LES,<br />
◦ experimental data: a) mean axial velocity (m/s) b) rms <strong>of</strong> axial velocity, (m/s) c) mean diameter<br />
(microns), and d) rms diameter (microns).<br />
