An extension of the analysis of Nield is made to more completely characterize the onset of convection in an infinite horizontal porous medium stratified by temperature and concentration. Comparisons are made with thermohaline convection in Newtonian fluids. Major differences lie in the concentration Rayleigh number dependence of the wavenumber at the marginal state of overstability and the dependence of the horizontal wavenumber in the “salt finger” region of stationary convection on both temperature and concentration Rayleigh numbers. Suggestions of geological applications and laboratory verification using a Hele‐Shaw cell are presented.read more

Heat Transfer in Geothermal Systems
TL;DR: In this paper, the authors discuss the mathematical formulation of convective heat transfer in geothermal systems and the prediction of reservoir behavior under production can be obtained by idealizing it as a saturated porous medium.

H.-J.G. Diersch,Olaf Kolditz +1 more
TL;DR: Weaknesses and inconsistencies of current model-verification methods are discussed as well as benchmark solutions for solving the coupled spatio-temporal convection process, consistent velocity approximation, and error-based mesh adaptation techniques.

Numerical study of double-diffusive natural convection in a porous cavity using the Darcy-Brinkman formulation
TL;DR: In this paper, the authors deal with natural convection in confined porous media, driven by cooperating thermal and solutal buoyancy forces, and the results are mainly analyzed in terms of the average heat and mass transfers at the walls of the enclosure.
