摘要
本文采用一种先进的测定浓度的光学方法,在环境风洞中对不同尺寸的粒子进行二维紊动扩散试验,得出了几种尺寸规格的粒子浓度分布图和粒子尺寸与垂向扩散系数之间的关系,结果令人满意。
In this paper the experiments of two-dimension turbulent diffusion for varying size particles are carried out in an environmental wind tunnel. By an advanced optical method used to survey the concentration of the particles, the concentration distributions of the particles in various sizes and the experimental relation between the vertical diffusion coefficient of particles and their size have been obtained,
