Numerical Study on Flash-Boiling Spray of Multicomponent Fuel

摘要

The sub models for flash-boiling spray of multicomponent fuel which take accoutfor fuel properties, vaporization process, bubble nucleation, growth and disruption inmulticomponent fuel droplet were added to KIVA3V. The numerical data usingthese models was compared with experimental data. The flashing spraycharacteristics from numerical simulation qualitatively showed good agreement withthe experimental results. In addition, it was confilmed that flash-boiling effectivelyaccelerated the atomization and vaporization of fuel droplets.
