| Outline of Final Research Achievements |
Prediction method of unbalanced snow accumulation on building roof using computational fluid dynamics (CFD) was developed. First, the snow depth distribution on the roofs was predicted without considering the effects of snow depth change on the flow field. The observational data of snow depth on the lower roofs could generally be reproduced. However, the specific undulations of snow near the roof step were not well reproduced by this method. Next, the effects of snow depth change on the flow field were considered through phased calculations. The study confirmed that the prediction accuracy was improved by considering these effects.
