dc.description.abstractNumerical modeling of snowdrifting is a useful tool for assessing the impact of building design on operations and facility maintenance. Here we outline the theory for the SAGE-PEDD snowdrift model that has application for determining snowdrift accumulation around buildings. This model uses the SAGE computational fluid dynamics code to determine the flow field in the computational domain. A particle entrainment, dispersion, and deposition (PEDD) model is coupled to SAGE to simulate the movement and deposition of the snow within the computational domain. The report also outlines areas of future development that upgrades to the SAGE-PEDD model should address.en_US
