CFD simulation on permeability of porous scaffolds forhuman skeletal system
Published 2022“…In this study, we simulated the permeability of hexagonal unit cells at different pore sizes (1.0 mm, 1.5 mm and 2.0 mm) and at different inlet velocities (0.001 mm/s, 0.5 mm/s and 1 mm/s) by using Computational Fluid Dynamic (CFD) in Ansys software. Our finding shows that pressure drop from inlet to the outlet of the unit cell’s pore increased corresponding to the decreasing of pores diameter. …”
