The study on the formation process of wind-blown snow can provide the scientific theoretical basis for the treatment of snowstorm disasters. The fundamental principle of the SPH approach is the independent particle decomposition of the computing domain. The discrete characteristics of snow particles in nature are remarkably similar to the physical properties of these computational particles, which can move through the control equation. This study develops a multi-field coupling SPH wind-blown snow sublimation model using the discrete features of snow particles and the SPH method’s characteristics. The model can depict when the physical characteristics of snowflakes vary over time and in different environments, and it can simulate how snowflakes collide as they travel through the air. Finally, the simulation results are compared with the experimental results and the numerical simulation results of others. The results show that the method is consistent with the previous research results, which verifies the accuracy and feasibility of the SPH numerical simulation method, and obtains some new conclusions.
