Gas slippage effect on microscale porous flow using the lattice Boltzmann method
TL;DR: A lattice Boltzmann method is developed for gaseous slip flow at the pore scale in microscale porous geometries and it is found that the gas permeability is larger than the absolute permeability of porous media due to the gas slippage effect.

X-ray microtomography characterization of porosity, permeability and reactive surface changes during dissolution.
Philippe Gouze,Linda Luquot +1 more
TL;DR: The results are used to validate the power law empirical model relating the reactive surface area to porosity proposed by Luquot and Gouze (2009) and investigate the spatial distribution of the effective hydraulic radius and of the tortuosity, two structural parameters that control permeability, in order to explain the different porosity-permeability relationships observed for heterogeneous and homogeneous dissolution regimes.
