RANS CFD simulations can be successfully used for simulating snowdrift on roofs in a long period of snowstorm

摘要

1 Introduction A long period of snowstorm, namely a snowdrift event, could last for hours to several days and the snow distribution on roof varies significantly during this period. Thus, for the heavy-snowfall regions, it is important to consider the snowdrift when evaluating the snow load on roof structures.
