Dispersion of Cd , Cr , Cu , Ni , Pb and Zn Particles in a Turbulent Air Flow

From the prospective of air quality, the dispersion of heavy metal pollutants has gain importance in recent past. The pollutants disperse from the point of release to the distant areas transporting contaminants there. Heavy metal pollutants in the form of fine particulate matter can be harmful to human health through inhalation. In this study the lateral dispersion of heavy particles is predicted with the help of experimentally measured values of the dispersion for copper particles. The experimental values of the dispersion for copper particles are taken from the literature. The stochastic technique is used to develop a rigorous simulation model for the dispersion of the copper particles. This technique helped in the generation of random fluctuations for the fluid (air) as well as for the heavy particle, copper. The random behavior of copper particle is applied on other heavy metals belonging to the same class. In this study the lateral dispersion of various heavy metal particles is predicted on the basis of their densities and particle sizes. The results so obtained make good sense and relate well with the density and size of the heavy metal particles.
