VOCs natural convective flow from the porous layer to an air region, including thermo-diffusion and diffusion-thermo effects was studied in this paper. Two domain model was used for problem formulation. The partial differential equations, governing the problem under consideration, were solved by applying a finite element approach. Weak form equation was used to link interface between the porous wall and the air region. The effects of thermo-diffusion and diffusion-thermo had been examined on flow, temperature and concentration fields. The results showed that the above mentioned effects had to be taken into flow, heat and mass transfer processes.
