Abstract
The sub models for flash-boiling spray of multicomponent fuel which take account for fuel properties, vaporization process, bubble nucleation, growth and disruption in multicomponent fuel droplet were added to KIVA3V. The numerical data using these models was compared with experimental data. The flashing spray characteristics from numerical simulation qualitatively showed good agreement with the experimental results. In addition, it was confilmed that flash-boiling effectively accelerated the atomization and vaporization of fuel droplets.
