“…It can be verified that, independent of the injection configuration, of the liquid flow rate and of the gas velocity, the size of the droplets measured experimentally were greater in the shorter axial distance (x = 0.12 m). The decrease in size with the axial distance x was also reported by Kihm et al [20]. Measurements taken downstream from the point of liquid injection, at x = 0.18 and 0.24 m, show D 32 to be close in size, suggesting that, once generated, the droplet size tends to stabilize quickly as it flows.…”
