Abstract
The main objective of this study was to develop further insight into the mass flux characterization of an effervescent atomization. The spray is injected through an industrial effervescent nozzle, and is measured using a newly developed coupled PDPA + IS method. Mass flux measurement of microscale droplets in multiphase atomization is a challenging task. The advanced laser diagnostics such as the phase Doppler particle anemometer (PDPA) are not capable of accurately measuring the droplet mass flux in a dense spray due to the high rejection of non-spherical droplets by the PDPA. A combined measurement of momentum rate data from the impulse sensor (IS) and velocity data from the PDPA provides a fairly reasonable estimate of mass flux data in effervescent atomization. Moreover, the mass flux data obtained by the coupled PDPA + IS will facilitate the estimation of the void fraction in multiphase dense spray, which will be very beneficial to the design of industrial multiphase nozzles.
