Description
  • A numerical model of an elastic tube was created. Our aim was to use the model for verification of blood vessel wall constitutive laws derived in our laboratory. The numerical simulation was based on electrical circuit analogy. The resulting non-homogenous hyperbolic system was solved using the finite volume method. In this case, a linear constitutive law was used and therefore the system was linear. Constant and harmonic boundary conditions (BC) were applied. The results under the constant BC were verified by Hagen-Poiseuille law. From the system with the harmonic BC, a pulse wave velocity along the tube was computed.

  • Pro elastickou trubici byl vytvořen numerický model. Naším cílem je použít model pro verifikaci konstitutivních zákonů pro cévní stěny navržené v naší laboratoři. Numerický model je založen na analogii s elektrickými obvody. Výsledný nehomogenní hyperbolický systém rovnic byl řešen metodou konečných objemů. V tomto případě byl použit lineární konstitutivní vztah. Konstantní a harmonické okrajové podmínky (OP) byly aplikovány na vstupu a výstupu z trubice. Výsledky případu s konstantními OP byly ověřeny exaktním výpočtem dle Hagen-Poiseuillova zákona. Z výpočtu s harmonickými OP byly počítány hodnoty rychlosti pulzní vlny podél trubice. (cs)
