Oxygen mass transfer in a membrane blood oxygenator (MBO) surrogate system has been addressed in this work. It consists of a slit for water circulation as a surrogate blood flow channel and a constant pressure oxygen chamber separated by an integral asymmetric hemocompatible polyurethane‐based membrane. The oxygenated stream enters a well‐mixed reservoir of constant volume, V, for the oxygen average concentration, , measurement as a function of time, t. In a range of short times, the linearity of vs. t allows the direct determination of the permeation fluxes , with no recourse to dimensionless correlations for the determination of mass‐transfer coefficients. The experimental fluxes are in very good agreement with the predictions based in unidimensional axial convection and unidimensional transversal diffusion. This custom‐made benchmark system allows the optimization of the flow and oxygen mass transfer for the design of a novel flat‐sheet MBO. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3756–3763, 2018

气/膜/液系统中的氧气质量传递是膜血液充氧器的替代品

这项工作已解决了膜血液氧合器（MBO）替代系统中的氧气质量转移。它由用于替代血液流动通道的用于水循环的狭缝和由一体的不对称血液相容性聚氨酯基膜分隔开的恒压氧气室组成。含氧物流进入一个恒定体积V的充分混合的储罐，以测量作为时间t的函数的氧平均浓度。的范围内的短的时间，的线性度与吨允许直接测定渗透通量的，在确定传质系数时不求助于无量纲的相关性。实验通量与基于一维轴向对流和一维横向扩散的预测非常吻合。这种定制的基准系统可以优化流量和氧气质量转移，从而设计出新颖的平板MBO。©2018美国化学工程师学会AIChE J，64：3756–3763，2018
