CFD and heat balance analyses on relationship between residential building arrangement and snow distribution

Abstract

In this study, the simulation method of snow distribution around buildings considering the effect of snowdrift and heat exchange on snow surface is developed by combining snowdrift simulation using CFD with the heat balance model. Furthermore, the relationship between residential building arrangement and snow distribution is investigated using above method. As a result, little difference has been observed in the results with different building arrangements given by only snowdrift analysis. On the other hand, large difference has been observed in the results obtained by snowdrift and snowmelt simulations. It is confirmed that snowmelt can be increased more by making the building distant large.
