Oxygen transfer performance in the membrane curved tube oxygenator

Based on the evaluation of oxygen transfer performance in terms of non-dimensional variables such as oxygen Sherwood number, fractional saturation and non-dimensional length, the conditions achieving the high performance of gas exchange is discussed. The non-dimensional length at the rated condition, in which the oxygen saturation at the outlet becomes 97%, was determined in the relation between the fractional saturation and non-dimensional length. Simultaneously the oxygen transfer performance expressed by oxygen Sherwood number has been evaluated in relation to the variation of non-dimensional length. Finally the design parameters such as internal diameter, tube length and residence time are determined based on the rated condition.
