| Abstract: | 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, |
