In view of developing an efficient artificial kidney module, the shape effect of hollow fibers was studied in terms of the dialysate flow. Two different fiber shapes: straight and wave-shaped ones, showed different dialysate flow distribution. We adopted a porous media model for the bundle of thousands of hollow fibers and studied axial and radial permeability for two kinds of fiber shapes from low to high fiber density. Present experimental results showed that the straight and wave shaped fibers had anisotropic permeability. Wave-shaped fiber shows larger permeability in radial direction than the straight-shape fiber. Due to this higher radial permeability, the pressure drop was lower for the wave-shaped fiber in the artificial kidney module.
