In order to study the continuous droplet impinging on solid surface, a pure Lagrange and meshless method, namely the smoothed particle hydrodynamics (SPH) method is used. The spreading, rebounding and splashing processes of the continuous droplet impinging on solid surface are simulated with the SPH, and the results are compared with experiments. It is shown that in the continuous droplets impinging on solid surface, there are many uncertainties with respect to the free surface of droplets. The effects of the secondary droplets and the Weber numbers might be the main factors that influence the impinging diffusion of droplets. The secondary droplets help the droplet spreading and splashing. With the increase of the Weber number, the dimensionless diameters of continuous droplets change faster. The simulation results truly reflect the impact process of droplets, to provide a reference for simulation analysis of similar impinging problem.
