Experiments on natural snow distribution around simplified building models based on open air snow-wind combined experimental facility

摘要: Abstract In previous studies, snowdrifts around different buildings have been investigated in wind or water tunnels, the outdoor environment, to ensure proper accessibility and safety of structures. The pattern is strongly connected speed incidence angle wind. Two sets experiments undertaken investigate influence on snowdrift accumulation a model another set explore two separated models. building wooden cube with dimensions 0.5 × 0.5 × 0.5 m. are carried out an open air snow-wind combined experimental facility, which situated outdoors, like tunnel snowfall simulator. facility can produce stable field environment for specific duration. During experiments, environmental conditions, temperature humidity were measured PC-4 automatic weather station. snow used came from natural 01/19/2016-01/22/2016. After each experiment, geometry was by surveying approximately 300 points model. results reveal that patterns distribution show close relationship surrounding buildings.
