Abstract :

Percolation is one of the most common phenomena in nature. For example water goes to ground or transport salt in reverse osmose. Many natural events or influence in the heat transfer, mass transfer issues have also been analyzed. With the advance of knowledge and enter into new areas, new issues emerge in the face of science. In this paper, the three main types of penetration, diffusion, mass diffusion and diffusion in the fluid will be discuses. The influence of molecular diffusion topics in molecular size and low displacements are often based on the concentration is investigated. The mass that occurs on a larger scale is usually different factors such as physical and environmental factors
