摘 要：
Compared with the simulation of pressure nozzles,the velocity direction of fuel at nozzles exit section must be concentrated on spray simulation of pressure swirl nozzles.Two-phase flow models used in commercial software were analyzed,and the analysis results show that Euler-Lagrange double phase flow model which was widely used in the simulation of pressure nozzles disagrees with spray simulation of pressure swirl nozzles at exit region.To simulated spray characteristic of pressure swirl nozzles,it may be more reasonable to use VOF two-phase flow model at exit section of pressure swirl nozzle,and then to use Euler-Lagrange biphase flow model at downstream position of the exit section,but it must be well considered that how to connect the two models.
