Scaffold, Negative Schwarz p, Permeability, Wall shear stress, TortuosityAbstract
This study aimed to investigate the effect of morphology on permeability and fluid wall shear stress of porous scaffold. Fluids passing through the scaffold were analyzed using the computational fluid dynamics (CFD) method, and tortuosity was analyzed using the finite-different analysis (FDA) method. Based on the results, the higher the porosity, the higher the permeability. In contrast, by increasing the tortuosity, the permeability decrease. Then, control curvature in the negative Schwarz p design has the potential to increase the permeability, consequently, decrease the specific surface area. Therefore, the design negative Schwarz p was proposed met the requirements for a good implant which the permeability value was in the range of trabecular bone.
