- W4382655455 abstract "Snowstorm disasters seriously endanger human life and the social economy. In order to find out the influence of the sublimation of snow on motion characteristic of snow-wind flow, based on Smoothed Particle Hydrodynamics (SPH), this paper simulates motion to propose the method and basic theory of the SPH model of snow-wind flow. The basic idea of the SPH method is to decompose the computational domain into independent particles. These computational particles carry their physical properties. And it can move with the governing equations, which is consistent with the discrete nature of snow particles. According to the advantages of the SPH method and the characteristics of snow flow, this paper improves and rectifies SPH theory, so that SPH shows its unique advantages in dealing with the coupling of two substances in the snow two-phase flow. This new model can able to achieving two functions: moisture diffusion and snow particle physical properties change with time and environment. And it can dynamically display the movement state of the salting snow particles of the whole snow-wind flow process to obtain each particle's speed, trajectory, and mass change. In this paper, the dynamic characteristics of snow particle swarm motion behavior are obtained through the microscopic analysis of a single snow particle motion physical quantity." @default.
