Mass transfer correlations for hollow fiber blood oxygenators have been determined experimentally using Newtonian and non‐Newtonian blood analogue fluids. The Newtonian fluids consisted of deionized water and glycerol/water mixtures. The non‐Newtonian fluids were prepared by adding small amounts of xanthan gum to the Newtonian blood analogue fluids. The rheological behavior of the non‐Newtonian blood analogue fluids was modeled using the power law. The diffusion of oxygen into and out of the Newtonian and non‐Newtonian blood analogue fluids has been studied. The liquid stream flowed outside and across bundles of woven hollow fibers, while the gas stream flowed inside the fibers.
