摘要：
The diffusive fluxes in porous media are inherently influenced by a reaction occurring at the internal surface. This investigation analyses this impact via a Fourier-mode analysis in a spherical coarsely porous model geometries consisting of random agglomerates of spheres. Trends are determined from the results and the overall impact for the given geometries estimated. CO 2022 The Author(s). Published by Elsevier Ltd.
