Through the analysis of two-stage atomization process, the mathematical model of the flight and cooling under which the droplet has been subjected to two times of crushing was established, and the simulation calculation was carried out. The atomization process parameters were analyzed by the simulation results and the preliminary verification was carried out through experiments. The results show that this model can basically predict the flight and cooling process of two-stage atomized droplets, and provide a theoretical basis for the selection of two-stage atomization process parameters
