A Study on Permeability analysis of 3-D Porous Models using Computational Fluid Dynamics (CFD

Permeability of scaffold is an important parameter which combines porosity, interconnectivity pore size and shape. It can influence on bone tissue engineering. The intrinsic permeability coefficient k of an open porous structure is ability to measure the fluid flow. Based on number of holes and standard pore diameter, 3D porous geometric models are created using commercial software SOLIDWORKS. In this study we found permeability co-efficient (k) of twelve different models with different shapes using Darcy?s law by satisfying all assumptions. For these models porosity may vary in the range of 20% to 50%.To obtain permeability co-efficient(k), pressure drops are found using CFD analysis for twelve porous models by considering boundary conditions from previous literatures and comparing permeability co-efficient(k) of porous models. - See more at:
