Popis: | To confirm the formation of dicrotic waveform pulse waves due to the elastic effect of arteries, a fully coupled fluid-structure interaction analysis of pulsatile blood flow in a very simple model using a finite element method was performed. An artery and the ejection of blood from the ventricle were modeled with a straight elastic tube and imposition of an intermittent pressure pulse wave, respectively. Significant dicrotic waves were observed for the results calculated with Young's moduli of 0.3 and 0.7 MPa. As the Young's modulus increased to 2.0 and 3.0 MPa, the level of dicrotic waves decreased. |
