| Abstract: | Applying CFD software platform FLUENT,using gas-solid two-phase flow theory,the paper simulates the impacts of uneven roof snow distribution in continuous snowing process under the action of various wind direction and wind speeds of self-defined roof.Through analyzing the snow distribution conditions,it finds out the most unfavorable impact of wind direction and wind speed in wind-inducing snow process,which has provided theoretical basis for perfecting structural static design and snow loading design standards. |
