BASIC INVESTIGATION OF MODELING FOR EROSION AND ACCUMULATION ON SNOW SURFACE

Numerical prediction of snowdrift around building using CFD

Abstract

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 the results of the field measurement and the wind tunnel experiment. It is confirmed that the snowdrift 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.
