  • The smooth particle hydrodynamics (SPH) method is used to analyze the mutual coupling motion characteristics between sands and the airflow, and the SPH numerical methods of sand flow is proposed and simulated in this study. Firstly, the SPH modeling method and basic theory about the sand flow is proposed and the SPH simulation platform of the flow of sand is established. Secondly, the SPH model and boundary conditions were used to simulate the movement of sand in the wind movement, the motion curve and characteristics of the sand are studied completely. Finally, by contrasting with the related research analysis, the effectiveness of the SPH method completed is verified. Allowing for the variability of the flow field, the way of loading (windy) and unloading (blowing-out) are applied in the SPH calculation model of sand flow, the motion curve and characteristics of the sand have been observed and comparatively studied. It will be helpful to further study of the constant dynamic nonlinear behavior of the sand flow by SPH theoretical basis and numerical analysis.
