Description
  • We developed a model of homogenized perfusion in a medium constituted by several transversely partially periodic layers, which enables us to approximate flow through different hierarchies of the porosity. We focus on modeling the perfusion of tissue parenchyma, being motivated by medical applications: a) the assessment of the local cerebral blood flow and b) the liver segmentation. At the level of small vessels and microvessels, the perfusion can be described using the Darcy flow in double porous structure consisting of 3 compartments: two mutually disconnected channels (small arteries and veins) and the matrix (microvessels and capillaries), represented as the dual porosity, where the permeability is decreasing with the scale parameter.
