Abstract
The secondary flow induced in the serpentine tube membrane oxygenator with steady and pulsatile blood flow enables to augment the gas transfer performance as have been seen in our previous studies. However, there is still some uncertainty in the effect of geometrical conditions on the gas transfer performance in the serpentine tube. In this study the oxygen transfer performance with steady and pulsatile blood flow was investigated for the serpentine tube with well-defined geometrical conditions such as coiling ratio and circular angle for the curved portion. The results of gas transferevaluation indicate that the augmentation of oxygen transfer can be achieved in the, fairly wide conditions of nature of blood flow and tubing configurations.
