Body Fluid Filtration through Two-Layered Capillary Wall Depending on its Porosity

  • Published:
Russian Physics Journal Aims and scope

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.
