Research on visualization of liquid phase LPG spray in the flashing boiling
A LPG spray test system is established by using a high speed CCD camera and schlieren technique, swirl injector and non-swirl injector of the same diameter are used to capture the images of instant sprays at the different injection pressure. Results show, with the increase of the injection pressure , the spray tip penetration increases while the spray angle decreases. The flashing boiling of LPG makes its spray tip penetration less than that of gasoline, while its spray angle is greater than that of gasoline. The swirl injector has promoted the atomization and evaporation of liquid phase LPG than the non-swirl injector, and hence will produce a more homogeneous air-fuel mixture.
