Description
| - Nedávno byl vyvinut homogenizovaný model prokrvené tkáně, který umožní lépe pochopit některé jevy spojené s difúzí tekutiny v tkáni a její deformací. Je patrné jak konkrétní forma geometrie a topologie mikrostruktury ovlivňuje tvar jednotlivých konstitutivních vztahů. Zejména lze sledovat, jak jednotlivé homogenizované koeficienty odrážejí specifické interakce na úrovni mikrostruktury. Homogenizace vychází z mikromodelu Biotova typu pro nestlačitelné složky média. V příspěvku jsou diskutovány některé otázky modelování hierarchické struktury stromu prokrvení, výpočet homogenizovaných koeficientů, zejména aproximace časové závislosti koeficientů modelu a popis přidruženého jevu vyhasínaj (cs)
- Recently a homogenized model of blood perfusion in deforming tissue was developed which is assumed to help in understanding some diffusion-deformation phenomena. One can see how the microstructural geometry and topology influence form of the homogenized constitutive laws and how individual homogenized coefficients reflect specific modes of interactions at the microscopic level. The micromodel considered in the homogenization procedure is based on the Biot model for the incompressible medium constituents. In the paper we discuss some modelling aspects related to hierarchical structure of the perfusion tree, the computation of the homogenized coefficients, namely approximation of the fading memory phenomena is addressed.
