Micro Abstract:
A LB model is presented to simulate advection-diffusion processes in porous media. Chemical reactions occurring on the pore surfaces causing dissolution require continuous surface adaptation. The approach utilizes the Cumulant LB model to model advection, a second LBM for the concentration of the chemical species, and an explicit surface dynamics solver governing the transient evolution of the surface geometry.
