山体绕流和尾流区气态污染物输送扩散规律的研究
- A STUDY ON THE TRANSPORT AND DIFFUSION OF GASEOUS POLLUTANTS IN A MOUNTAIN ROUNDING FLOW AND LEE EDDY
- 摘要：采用瞬时烟线仪与迪沙(DISA)热线风速仪相结合的方法探测了山体的绕流区和尾流区结构。试验结果表明,山体的绕流和尾流对低架源排放的气态污染物扩散影响甚大,山体绕流可改变烟流的地面浓度分布.结果还表明,我们所用的探测流向的方法较为有效和准确.
- Abstract：A wind tunnel experiment was carried out to characterize the transport and diffusion of gaseous pollutants, emitted from a plant near a mountain, in the mountain-rounding flow and lee eddy,whose structures were measured by using a smoke line meter and a DI-SA heat line anemometer. It was found that the mountain-roundingflow and lee eddy had a significant effect on the diffusion of gaseous pollutants from a lower source and caused a change in the distribution of smoke plume concentration at ground surface.
