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