Abstract
The secondary flow induced in the serpentine tube with pulsatile flow is enable to augment the gas transport as have been seen in the helically coiled tube. In this study the gas transfer performance with pulsatile flow is investigated experimentally for the curved tube with periodically varying curvature (serpentine tube). The effects of frequency, amplitude of pulsation and the geometrical conditions of curved tube on the oxygen transfer are clarified, and the augmentation of oxygen transfer with pulsatile flow is revealed for serpentine tube.
