WebIt has been demonstrated that flash boiling atomization can remarkably reduce wall impingement (and thus soot emissions, improve thermal efficiency, and reduce cycle-to-cycle variation [6-9], the combustion near the injector tip is still rich, and yellow sooty flames were spotted [10, 11]. WebAug 1, 2008 · Flash-boiling atomization is one of the most effective means of generating a fine and narrow-dispersed spray. Owing to its complexity its potential has not been fully realized to date. The paper...
State of the art review of flash-boiling atomization
WebFrom the result of the study, a simple approach was proposed to model a low-pressure flashing spray based on a conventional evaporation model, with modified input parameters to include the flash-boiling effects on droplet size, spray penetration and angle, and the spatial droplet distribution. WebApr 8, 2013 · In this study, the flash boiling spray from a multi-hole DI injector was investigated in a constant volume chamber using various laser diagnostic techniques. The macroscopic spray structure, flow field, droplet size and vapor concentration were obtained under typical conditions encountered in the DI engine operations. the wadham trading company
