| Abstract | Atomization and droplet dynamics of a gas-liquid two-phase jet were investigated experimentally, with the particular interest in the influence of mass loading ratio (the ratio of droplet mass flow rate to the carrier-phase mass flow rate, ranging from 0.60 to 3.23) on the jet atomization. Droplet size and velocity at selected positions were obtained by employing Phase Doppler Particle Analyzer (PDPA), combined with backlit illumination for spray visualization. Droplet transport characteristics are substantially influenced by the mass load ratio. Char-acterization of the local gas flow velocity by using droplets smaller than 5 mu m reveals a highly turbulent jet with Reynolds number exceeding 5 x 10(4), implying the possibility of droplet turbulent breakup. Critical equilibrium location x(crit )between droplet breakup and coalescence is close to the nozzle exit and a positive correlation is found between mass loading ratio and x(crit). Exaltation of mass loading ratio increases the droplet size and de-creases the velocity. Quantification of droplet collision outcome indicates a relatively high probability of coa-lescence, which explicates the downstream increasing of measured droplet Sauter mean diameter along the centerline of far-field jet. |
