Predicting permeability via statistical descriptors of morphology on polydisperse foams including membranes
Résumé
Quantitative structure-property relationships are crucial for the understanding and prediction of the acoustical properties of complex foams. For fluid flow in polydisperse foams, characterizing the pore size distribution and membrane content facilitates prediction of permeability, a key property that has been extensively studied in material science, geophysics and chemical engineering. In this work, we propose a formula to predict the permeability of polydisperse foams including membranes via microstructural descriptors which can be derived from X-ray microtomography and scanning electron micrographs.
