| 摘 要： | 建立血液流动的剪切稀化模型,并对3-D微管道内血液多相流动进行数值模拟,得到的结果与实验数据比较显示,该模型不仅能预测微管道内速度分布,还可以体现微尺度下血液流动的F-L效应.为了探索无膜透析可行性,利用该非牛顿两相流模型对T型微槽道内血液透析过程进行数值模拟,结果表明,血浆中质量扩散系数较大的组份很容易从血液扩散到透析液中,实现了组份分离.

| Abstract: | A non-Newtonian shear-thinning model is shown and applied to multiphase flow simulation in 3-D micro-tubes.The model is validated by comparing simulation and experimental results.Velocity simulated agrees well with experimental data and shows F-L effect in microscale hemodynamics.To investigate non-membrane hemodialysis,we simulate hemodialysis in a T-shape mixer.Simulation indicates that components with larger mass diffusion coefficient pervade sufficiently and they can be separated from other components. |
