Fuel spray and its measurement techniques

Research output: Contribution to journalArticle

Abstract

In this report, fuel spray, especially engine application, and measurement techniques for fuel injection characteristics, such as break-up of liquid column, spray angle, penetration length, followability of droplets, droplet dispersion, entrainment vortex structure and so on, are explained. Microscopic visualization of liquid column break-up process in a gasoline PFI injector and simultaneous measurements of droplet diameter and velocity using phase Doppler anemometer (PDA/PDPA) are introduced as examples of measurement techniques. Obtained knowledge of spray and atomization characteristics using these techniques are mentioned in the case of unsteady spray from a gasoline injector.
