Abstract
Applying Computational Fluid Dynamics (CFD) technique, numerical investigationshave been carried out to simulate wind flow conditions on various roof configurations. Usingthe computed mean wind flow field, the snow-drift distributions on these roof configurationsare calculated. This study demonstrates that the CFD technique can be effectively applied inthe earty stage of the design process as a predictive tool for forecasting snow accumulationon various roof configurations. Efforts are also made to quantify the validity of modelpredictions through comparisons with field observation and wind tunnel data.Peer reviewed: YesNRC publication: Ye
