The paper proposes a new filtration model for studying the distribution of one component of the two-component body fluid and the fluid velocity in a two-layered capillary in stationary conditions. The proposed mathematical model considers such important phenomena as concentration expansion and viscosity-concentration dependence. The fluid flow correlates with the Brinkman model. Identified are the dimensionless groups, which connect different physical processes with each other. It is shown, how the model parameters affect the body fluid filtration via the two-layered capillary wall of various porosity. The motion and distribution of the fluid component are analyzed for different properties (porosity, phase mobility and size) of the inner porous layer.

该论文提出了一种新的过滤模型，用于研究静止条件下两组分体液中一种组分的分布和两层毛细管中的流体速度。所提出的数学模型考虑了诸如浓度膨胀和粘度-浓度依赖性等重要现象。流体流动与 Brinkman 模型相关。确定的是无量纲组，它们将不同的物理过程相互连接起来。显示了模型参数如何通过不同孔隙率的两层毛细管壁影响体液过滤。针对内部多孔层的不同特性（孔隙率、相迁移率和尺寸）分析流体组分的运动和分布。
