Basic investigation of modeling for erosion and accumulation on snow surface Numerical prediction of snowdrift around building using CFD

This paper presents the investigation of the prediction models for snowdrift around a building using CFD. Special attention is paid to prediction accuracy of the modeling for erosion and accumulation on snow surface. The computations are applied to the snowdrift around a cubic building model. The results obtained by CFD models are examined by the comparison with there-softs of she field measurement and the wind tunnel experiment. It is confirmed that the snowdril: patterns predicted by all proposed models correspond with those of the field measurement and the experiment. However some differences are observed in the predicted snow depth near the building among the different modeling methods.
