Flow Analysis of Viscoelastic Tube Using One-Dimensional Numerical Simulation Model
In order to analyze the pressure wave propagation in circulatory systems, we previously presented a one-dimensional numerical flow simulation model that describes wave propagation in silicone tubes well and shows that the viscoelasticity of the tube has an important role in the wave propagation.

| description | In order to analyze the pressure wave propagation in circulatory systems, we previously presented a one-dimensional numerical flow simulation model that describes wave propagation in silicone tubes well and shows that the viscoelasticity of the tube has an important role in the wave propagation. In the present study, by comparison with experimental results, we show that the one-dimensional numerical model describes well the propagation of small pressure waves in silicone tubes even when their deformation compliance and viscoelasticity change independently, provided that appropriate values of the viscoelastic parameter are used. |
