The purpose of this study is to predict snowdrifting conditions before building an Antarctic station. For this purpose, the studies conducted by Japan and Germany to predict snowdrifting were investigated first. Computer simulation and physical scale model tests on the site were used as evaluation methods for snowdrift prediction. According to the test result, it can be known that CFD and the physical scale model tests cannot predict the amount of drifted snow, but can predict snowdrift patterns.
Based on the findings, the actual snowdrifting conditions measured around the temporary camp built on the Jangbogo Station site and the numerical flow analysis were compared, and the result of actual measurement and the result of CFD analysis showed similar snowdrift patterns. Snow accumulated long on the ground like a tail because vortex behind the building and the building structure slowed down the speed of snow.
The analysis of airflow around the Jangbogo Station conducted based on the studies conducted previously shows low speed airflow distribution in the east of the building due to the wind direction from west. Especially, if there is airflow with snow behind the pillar of the Jangbogo Station where the tail of vortex and downwind meet, large snow accumulations is predicted in the east of the building. And, in the event that downwind carries snow toward the central point of the Jangbogo Station, large snow accumulations is predicted behind the central core.
