The current numerical study was conducted to analyze fluid flow within hollow fiber membranes of the artificial lungs. The hollow fiber bundle was approximated using a porous media model. In addition, the transport equations were solved using the finite element formulation based on the Galerkin method of weighted residuals. Comparisons with previously published work on the basis of special cases were performed and found to be in excellent agreement. Different flow models of porous media such, Darcy model, Brinkman-extended Darcy, Forchheimer-extended Darcy, and the generalized flow models, are considered. A Newtonian viscous fluid model for the blood was used. The effects of Darcy number, inertia parameter, Reynolds number, porosity, and fiber diameter are analyzed in this investigation. Results are presented in terms of streamlines and pressure distribution within the hollow fiber membrane.
