The pulsatile flow in the helically coiled tube induces the composite secondary flow which is different from that appeared in the steady flow. This type of secondary flow is enable to cause the further augmentation of mass transfer. In this study the gas transfer performance with pulsatile flow is investi-gated experimentally for the helically coiled membrane oxygenator by using the scotch-yoke pulse generator. The effects of frequency and amplitude of pulsation to the oxygen transfer are clarified and the augmentation of oxygen transfer is obtained up to 70% compared with that in the steady flow under the experimental conditions taken.
