| 摘 要： | 采用两相流理论模拟风荷载雪漂作用,认为空气相和雪相的关系为单向耦合,雪在风(空气相)的作用下发生漂移.对通用计算流体动力学软件FLUENT进行了二次开发,计算了在风作用下积雪发生迁移后屋盖表面的雪压分布,并对雪荷载改变量以及雪压分布的规律进行了分析,为结构设计提供了依据. |
| 关 键 词： | 大跨度屋盖结构 计算流体动力学 两相流 雪漂 雪荷载 |

| Abstract: | Snow drifting in wind is considered in this paper as a two-phase flow.The mixture of air and snow is assumed to be one-way coupled so that the air phase can be treated as unaffected by the airborne snow. The numerical simulation employs the commercial computational fluid dynamics(CFD) software,FLUENT,with additional user C code added to model snow drift.The paper presents an analysis of the regularity of the redistribution of snow loads on the Roof of Terminal 3,providing a basis for design of structure. |
| Keywords: | large-span roof structure computational fluid dynamics two-phase flow snow drifting snow load |
