Abstract: This paper presents a numerical investigation on snow accumulation caused by ambient snowdrift. According to the wall shear mechanism and spatial mixture theory, a numerical prediction model for snow accumulation has been developed, and the results obtained from the prediction model are compared with the measured results. The comparison indicates that the prediction model adopted in this paper can reflect the deposition phenomenon more directly and expand the value range of the model parameter. Due to the adoption of double dynamic model indicators, the prediction results are more reasonable than the results obtained by the other numerical methods. The prediction model adopted in this paper can be used to simulate the snow accumulation around other ground objects with different shapes.
