Gas transfer to blood flowing in coiled circular tubes
Transfer of physiological gases to blood flowing laminarly in helically coiled permeable-walled tubes was investigated; it is shown that helical coiling of tube leads to significant improvement in gas transfer rates because of induced secondary velocities; gas transfer rate for this coiled tube geometry depends on Reynolds number, Schmidt number, and ratio of helix to tube diameters; oxygenator using coiled tubular membranes would be limited by tube length required to eliminate carbon dioxide; membrane oxygenator utilizing coiled, tubular membranes is shown to be feasible.
