Description
  • A numerical model of pulsatile flow through an elastic tube was created. From the numerical model, the pulse wave velocity (PWV) was obtained. The PWV is an important parameter influenced among others by the mechanical properties of the vessel wall. Keeping all other parameters under control, the dependency of the PWV on the material constitutive law of the tube wall can be observed. In our laboratory, the PWV in an elastic tube is measured experimentally. Therefore, it can be compared with the numerical results and validate the constitutive model independently on parameter fitting from the static tests. In this paper the numerical results for nonlinear material model for an elastic latex tube were compared with our experimental data presented in [1] to evaluate the verification method.

  • Byl vytvořen numerický model pulzního proudění elastickou trubicí. Z modelu byla získána rychlost pulzní vlny. Ta je důležitým parametrem ovlivněným mimo jiné mechanickými vlastnostmi cévní stěny. Experimentálně získaná rychlost pulzní vlny může být porovnána s rychlostí vypočtenou na základě našeho konstitutivního modelu a tím může být model ověřen. V tomto případě jsou porovnány experimentální a numerické výsledky pro latexovou trubici. (cs)
