摘要：Porous materials are essential in applications like impact absorption, thermal management, tissue engineering, and vibration damping, making their detailed study crucial. Key parameters in pore structure characterization include porosity, pore distribution, types, aperture size, shape, tortuosity, pore size distribution, specific surface area, and permeability. This study numerically simulates the permeability of two Triply Periodic Minimal Surfaces (TPMS) structures—Primitive and Gyroid—and two strut-based lattice structures—Diamond and Iso-truss. The analysis was conducted under steady-state conditions, with variations in porosity levels (60%, 70%, 80%, 90%), Reynolds numbers (Re) of 10, 50, 100, 150, 200, and 250, and a lateral length of 3 mm. Results indicate that higher porosity correlates with higher permeability, while increasing Re lead to higher pressure drops, reducing permeability. Among the structures, the lattice Diamond shows the highest permeability, while TPMS Primitive generally has the lowest.
