An inverted spherical model of an open-cell foam structure

An inverted open-cell foam model based on hexagonal close packing symmetry is proposed for open-cell foams with different configuration of struts. The novel model predicts the properties of the broad spectrum of open-cell ceramic and metallic structures. According to the proposed model, the specific surface and hydraulic permeability can be derived from experimentally measurable parameters such as porosity and cell diameter. The calculated parameters are in good correlation with the experimental data even without introducing additional empirical coefficients.
