| 摘 要： | 风洞模拟实验是研究起、降尘过程最有效的手段。前人只研究了低湍流度气流中,平坦表面的实际起尘过程。作者提出一组扩展的相似性原则,用于模拟大气边界层湍流及复杂地形对趋、降尘过程的影响及防尘风障在此条件下的减尘效率,并得到一系列有意义的结果。

| Abstract: | Wind tunnel modeling experiment is probably the most effective measure to investigate dust emission and deposition, Previous authors studied only the emission process from plane dust surfaces into low turbulence intensity flows.In this paper, present authors propose an extensive system of similarity principles, which has been used in wind tunnel experiments to study the effect of atmospheric boundary layer turbulence and complex terraia on dust emission and deposition and to study the effectiveness of, windbreaks on presenting dust emission, The experiments have significant results. |
