摘要/Abstract

摘要： 应用Graetz-Leveque问题的前进边界理论的修正近似解,进一步分析了半透膜阻力对氧传质速率的影响,获得了与Graetz-Leveque问题精确解非常接近的(相对偏差在6.58%以下)用于计算平板膜式氧合器中氧传质系数的简单分析表达式.并提出了基于氧传质速率计算的该类氧合器通道长度设计的临界判据.

Abstract: In this paper, an equation for the local blood-side Sherwood number is derived from the advancing front theory (AFT) for mass transfer of oxygen in a parallel plate membrane oxygenator. The maximum deviation of the approximate solution in comparison to the classical Graetz-Leveque solution is reduced to 6.58% from 22.3% by srinivasan et al. The simple analytical expressions enable analysis of the effect of oxygen reaction and membrane resistance on mass transfer. The design criteria for the channel length of a parallel plate membrane oxygenator are proposed.
