The Effect of Hollow Fiber Arrangements on the Performance of Membrane Oxygenator Modules

In modern membrane oxygenators, microporous hollow fiber membranes are used in order to perform oxygen transfer from gas phase into blood phase. Since the major resistance to gas transfer is due to the blood side mass transfer boundary layer, various methods have been examined to thin the liquid film and improve oxygen transfer rate. In this study several mass transfer and friction factor correlations for different configurations of hollow fiber membrane oxygenators are studied and compared to highlight the key factors affecting their effectiveness and efficiencies. The results indicate that the arrangement and size of hollow fibers play important roles in the performance of the membrane oxygenators. These modeling and correlations can provide useful guidelines for designing efficient membrane oxygenators.
