Aiming at the spraying process of airless atomization spraying,a coating film forming model based on Euler-Lagrangian method is proposed.A Rosin-Rammler atomization model was established.The force equilibrium equation of the dis-crete phase and the continuity equation and momentum equation of the continuous phase are established in the flow field.The mo-mentum equation of the continuous phase is closed by the standard k-ε model.The continuity equation and momentum equation are established in the adhesion deposition model to solve the coating thickness.The computational domain grid is divided into nozzle computational domain and plane computational domain,and the mixed grid of tetrahedron and hexahedron is used to di-vide the computational domain.PC-SIMPLE algorithm was used to solve the model.Finally,the dynamic spraying simulation is verified through experiments,and the numerical simulation results are in good agreement with the experiments as a whole.It is proved that the established film forming model can be used to study the film forming process of airless spraying.
