Numerical Simulation Model with Viscoelasticity of Arterial Wall

摘要: Numerical flow simulation is useful for understanding fluid phenomena such as blood or pulse wave propagation in the systemic arteries. For numerical analysis of intravascular flow, it important to consider not only incompressible assumption and viscosity but also viscoelasticity vessel wall; however, vivo complicated because unsteadiness pulsatile complex viscoelastic properties wall. In order conduct a vessel, effective use one-dimensional distributed parameter model, which can analyze along with axis. This pressure, volume cross-section tube every section element are defined time change analyzed.
