Flash Boiling in Sprays: Recent Developments and Modeling

Abstract

This study aims to cover the modeling of flash boiling effects
in the sprays. There is a lack of an economical and computationally efficient
methodology to analyze this complex phenomenon. Flash boiling
being an essential phenomenon in combustion engines is the cause
of change in the spray structure, cone angle, liquid penetration length,
droplet distribution, etc. The paper revisits various models used to capture
the effect of the flash boiling phenomenon and identifies the drawbacks
and challenges, respectively. The whole phenomenon is divided
into various stages and discussed stepwise. It tries to address the issues
related to the gaps in modeling.
