Near-nozzle spray and spray collapse characteristics of spark-ignition direct-injection fuel injectors under sub-cooled and superheated conditions
TL;DR: In this paper, the effects of fuel temperature, ambient pressure, nozzle L/D ratio, and nozzle number, as well as near-nozzle spray characteristics and spray collapse phenomenon under superheated conditions, were studied.

Simultaneous two-phase flow measurement of spray mixing process by means of high-speed two-color PIV
TL;DR: In this article, a two-color PIV optical diagnostic technique has been developed and applied to simultaneously measure the velocity flow fields of a multi-hole spark-ignition direct injection (SIDI) fuel injector spray and its ambient gas in a high-pressure constant volume chamber.

Characteristics and correlation of nozzle internal flow and jet breakup under flash boiling conditions
TL;DR: In this article, a two-dimensional optical transparent nozzle was adopted to study in-no-zzle multiphase flow characteristics as well as spray characteristics outside of the nozzle, and the correlation between the internal flow and spray liquid jet breakup was established and the impact of the gas-liquid correlation on the properties of flash boiling sprays was presented.
