Difusion in porous media refs to te te process by which particles spread treagh a material contraing interconnected pores. This fenomenon is important in fields such as hydrogeology, petroleum compleering, and environmental science. Understanding how difusion works helps in predicting thae movement of contaminatinants, fluids, and gases witsin porous structures.

Fundamentals of Diffusion

Diffusion concentration gradients, where particles move from areas of high concentration to low concentration. In porous media, this process is influcencd by pore structure, fluid concentraties, and temperature. Thee rate of diffusion can be descbed using Fick 's lags, which relate flux to concentration gradients.

Factors Affecting Diffusion in Porous Media

Several factors impact difusion rates with in porous materials:
