Sažetak
This research presents a numerical modeling of spray process using the Euler-Eulerian multi- fluid approach where standard secondary breakup model was improved and validated. Improvements include an introduction of probability distributions and a breakup factor into the secondary atomization model. They distribute calculated mass transfer into a number of Eulerian classes, thus alleviating the excessive creation of small diameter droplets. The model is validated by simulating high-pressure liquid fuel injection into cold, non-reactive environment. The results are compared with experimentally obtained data of spray characteristics including spray tip penetration, Sauter mean diameter, spray angle, as well as droplet number and volume distributions. The modified model shows improvements in description of spray breakup process in the Euler-Eulerian multiphase approach.
