... microfibers. Gas transport is found to be enhanced by flow pulsatility, the increase of the Reynolds number or flow rate, and the decrease of void fraction in the squared array geometry. Compared to the squared array geometry, the staggered array geometry produces a higher gas transfer at relatively high void...

... conditions that enhance gas transport; and providing pressure drop data that indicate the degree of flow resistance or the demand on the right heart in driving the flow through the fiber bundle. The results show that pulsatile flow improves the gas transfer to the fluid compared to steady flow. The degree...
