The following are concluded for the High Discharge Swirl Atomizer, through theoretically analyzing liquid film disintegration, analysis and experiment for a liquid immersion process, and the measurement of liquid film thickness.
(a) A new liquid immersion process is developed, presenting the method of determining a mean droplet diameter.
(b) Empirical formulae are given for the atomization characteristics and discharge characteristics with the figures of a swirl atomizer.
(c) Empirical formulae are derived from the film thickness-atomization characteristics, and atomization characteristics are summarized, proposing a mean droplet diameter nomogram widely applicable to a swirl atomizer.
