Numerical Simulation of the Snow Icy Phenomenon of the Bogie Motor

Abstract

In this paper, the turbulence model of SST k-ω is used to simulate the air flow field characteristics of the bogie motor, and the velocity field and pressure field of the bogie area are analyzed. The results show that the structure of the bogie is complicated, and the airflow with snow particles will impact the heating element in the bogie area. The positive pressure on the motor is larger and the entrained snow particles are rapidly melting and freezing. At the same time, there are a lot of low-speed vortexes above the motor, where the snow particles may be stationary and fall onto the surface of the motor. As the speed increases, the snow particles are increased, and the snow accumulation is more serious.
