Abstract
We investigate some aspects of thermodiffusion in saturated porous media in the presence of both density-and temperature-driven single-phase flow. This type of flow is sometimes referred to as thermohaline flow. We also review some fundamental thermodynamic concepts that are necessary for the formulation of the examined problem and compare our approach with some other models of thermodiffusion available in the literature. Our constitutive description and mathematical modeling are framed within the hybrid mixture theory. Finally, we show and discuss the results of numerical simulations of some selected test cases in which thermodiffusion as well as thermohaline flow are considered.
