Passive scalar dispersion along porous stratum with natural convection
Chenglong Hu, Ke Xu, Yantao Yang
We investigate horizontal dispersion of a passive scalar in a porous stratum with Rayleigh-Darcy convection initiated by a geothermal gradient. While increasing Rayleigh number ($R…

From Darcy flow to convective flow: pore-scale study of density-driven currents in porous media
Junyi Li, Yantao Yang, Chao Sun
We conducted a series of pore-scale numerical simulations on convective flow in porous media, with a fixed Schmidt number of 400 and a wide range of Rayleigh numbers. The porous me…
