SPH numerical simulation of snow drift movement with complex particle size

In this paper, a meshless method (SPH) is used to simulate the movement of snow drift with complex particle size. The characteristic point of SPH method is that the problem domain is transformed into particles containing physical information, and the particles carrying physical information are solved to get accurate results. Therefore, SPH can accurately describe the physical information of any snow particle in the microscopic study of snow drift, which is also a unique advantage of SPH in the study of snow drift. In this paper, the SPH modeling method of complex particle size snow particles are described, and the snow drift model is optimized, which makes the initial SPH snow drift model conform to the random accumulation of snow particles in nature. In this paper, the snow drift structure of complex particle size is numerically simulated, and the macro and micro results obtained by simulation are analyzed. The conclusions obtained are compared with the conclusions of other scholars, and the feasibility of SPH method to simulate the movement of snow drift with complex particle size is verified.
