BREAKUP TRANSITIONS WITHIN DENSE SPRAYS
要約
This study evaluates the influence of neighbor—induced changes to the local environment of a droplet in a dense spray on the droplet breakup regime. To this end, previously published breakup data exhibiting a mismatch between the expected isolated droplet breakup transitions and the observed breakup transitions within dense spray environments are re-examined. We find that secondary breakup of droplets within a dense spray is adequately described by the criteria developed for isolated droplets if neighbor—induced changes to the local environment (increase in local vapor concentration, drag reduction caused by leading droplets, and surface tension variation with liquid—gas density ratio) are correctly taken into account when evaluating the criteria for breakup regime transitions.
