人工造雾成雾过程微物理性能分析

通过对人造雾宏观性能和微物理性能变化过程的观测与分析,研究了人造雾成雾过程和成雾机理,并结合对云雾生长理论的分析比较了实际雾滴粒径分布范围、生长时间等与理论计算结果的异同。结果显示人造雾的雾滴粒径和生长时间与理论计算结果基本相符,但其具体的生长过程与理论过程有所差别;人造雾与天然雾相比,雾滴数密度稍大,但雾滴粒径和含水量稍小,雾滴谱分布特点有所不同。

The Analysis of the Microphysical Performances of the Artificial Fog Forming Process

The macroscopical properties and the changing of microscopical performances of artificial fog have been studied.In terms of the discussion of the forming theory of fog,the difference between experimental results and the theoretical calculation was compared.The results showed that the granularity and liquid water content of artificial fog droplet were a few less than that of the natural fog while the droplet concentration of artificial fog was higher than that of natural fog.Furthermore,the fog size distribution was different between them.
