A simulation study of analyzing the snow accumulation on the bogie regions of a high-speed train was conducted based on the Realizable k-ω turbulence model coupling with the discrete phase model (DPM). A series of snow-wall bonding criteria, including surface threshold friction velocity and capture angle, were proposed by considering the interactions and collisions between flow and particles. The rationality of the parameter settings was discussed by using control variable parameter analyses based on the prototype test provided by Paradot. The simulation results were compared with the prototype test. The parameter settings adapted in the previous studies for the snow-wall bonding might be relevantly low. The relative values in the criteria are 1.0 m/s and 60°, respectively. Then the validated parameter settings were used, and the snow accumulation estimations on the bogie regions of a high-speed train in China were conducted. Results show that snow accumulations are mainly located on the leeward side (surface) of each bogie component and connecting corners, especially the frame beam and the gear reduction box. The snow-covering areas of the rear bogie are more dispersed.
