Flash Boiling atomization is one of the most effective means of generating a fine and narrow-dispersed spray. Unless its complexity its potential has not been fully realized. In This Paper, a three dimensional chamber has been modeled with a straight fuel injector. Effect of Flash Boiling has been investigated by computational fluid dynamics (CFD) techniques. A finite volume approach with the ...

A quantitative structure property relationship study of the flash point of a diverse set of 271 compounds provided a general three-parameter QSPR model (R(2) = 0.9020, R(2)(cv) = 0.8985, s = 16.1). Use of the experimental boiling point as a descriptor gives a three-descriptor equation with R(2) = 0.9529. Use of the boiling point predicted by a four-parameter reported relationship gives a three-...

This study aimed to investigate the influence of flash-boiling conditions on liquid propane sprays formed by a multi-hole injector at various injection pressures. The focus was spray structures, which were analysed qualitatively and quantitatively means spray-tip penetration global angle. effect flash boiling evaluated in terms trends observed for subcooled conditions. Propane injected commerci...

The connectivity index chi can be regarded as the sum of bond contributions. In this article, boiling point (bp)-oriented contributions for each kind of bond are obtained by decomposing the connectivity indices into ten connectivity character bases and then doing a linear regression between bps and the bases. From the comparison of bp-oriented contributions with the contributions assigned by ch...

Flash boiling and plume interaction are common phenomena occurring in gasoline direct injection (GDI) spray at throttling low load engine conditions. Combined with optical engines low-pressure vessels, several techniques, such as backlight imaging, Mie-scattering, laser sheet imaging have been employed to study the flash morphology. However, 2D images resulting from these techniques (projection...
