| 中文摘要: |
| 基于k-ε湍流模型建立了大气风场的数学模型，本文计算了不同粗糙度复杂地形下风场，模拟结果给出了不同环境风速条件风场的速度等值线，粗糙度为0.1 m的地形的气流输运能力要大于粗糙度为1.0 m地形，这为下一步研究污染物的迁移扩散打下了基础. |

| Based on k-εturbulent mathematical model,the model of air flow field were built.Air flow field were computed on complex terrains on different roughness degrees.The velocity contours of different environment air flow field were given in this paper.The transportation capacity of the terrain for roughness degree of 0.1 m is greater than the terrain for roughness degree of 1.0 m,which provides the foundation for next contamination migration and diffusion research. |
