| 摘 要： | 本文研究了平板膜式氧合器中不伴有氧合反应时氧在血液中的传质过程。根据氧在血液中传递特性建立了数学模型。通过解扩散微分方程,求得了氧在血液中的平均浓度,平均Sh(?)rwood数的理论表达式,并在硅胶平板膜式氧合器中进行了实验验证。在实验范围内(Re=0.8—25),还把Sherwood数关联成下列准数形式: (?)=0.055 Re~(0.59)Se~(0.33) 该式可供设计平板膜式氧合器时参考使用。

| Abstract: | The mass transfer problem of oxygen in a plate membrane oxygenator without oxygenation was studied. For oxygen-blood system the mathematical model was presented. It was established on the basis of mass transferring chracteristics of oxygen in blood medium and resulted by the method of mathematical developing, i. e. by solving the relevantdifferential equations of diffusion. The theoretical expression of dimentionless average concentration and Sherwood number were obtained in this way and the results was apparently supported by experimental facts in a silicone membrane oxygenator.The dimentionless correlation is given as follows:(?)_(LO)=0.055 Re~(0.59)Sc~(0.33)which, according to authors' opinion, can be used with advantage in the designing work of plate membrane oxygenator. |
