Visualization of spatial distribution of the droplet size and velocity in flash boiling spray with extended glare-point imaging technique

Flash boiling is an effective way to improve the atomization quality. Droplet diameter and velocity distribution of the flash boiling spray extremely impact the mixture formation of direct injection engines. We visualize and measure the spatial distribution of the droplet size and velocity of flash boiling spray with extended glare-point imaging technique in this paper. An improved correlation-based processing algorithm for droplet...
