Investigating the Characterization of Pore Size Distribution and Permeability, Capillary Water Absorption in Porous Media Based on Entropy Theory

Energy Science &Engineering, EarlyView.
ABSTRACT The performance of porous media, such as capillary water migration and permeability, is significantly influenced by the complexity of the pore structure. The pore complexity can be characterized by the fractal dimension of the pore structure (D f ${D}_{f}$) and the fractal dimension of pore tortuosity (D T ${D}_{T}$).
