The study and modeling process of effervescent atomization are reviewed. The mechanism of droplet events and the treatment of liquid fragmentation process and dispersed particles are systematically presented, which includes the primary atomization of Newtonian and non-Newtonian fluid, instability analysis, turbulence treatment, particle tracking, secondary atomization and droplets collision. The review on the sub-models involved in the simulation of effervescence is followed by a summary of the achievements of modeling. First is the validation of models; then the parametric study is summarized; the third part introduces the fitting formula of droplet mean size and impinging factors, and finally the scope of future study is indicated.
Understanding the atomization spray process is not only of academic interest but also is important to various industry applications. Signifi-cant experimental investigations concerning spray behavior have been conducted in the past. Fundamental understanding of the spray pro-cess is, however, still lacking and lags behind applications due to the high complexity of its stochastic behavior. Prof. LIN Jianzhong
