Evaluation of the Impact of Arterial Wall Viscosity in Pressure Morphology by Means of a Simplified 1D Model

Introduction: The interest on computational simulations of biomedical models has increased in the last years. Nevertheless, the viscous properties of vessel all are usually neglected. Materials and Methods: A 1D model of blood flow and its interaction with the arterial wall was implemented. Non-viscous modeling and the addition of a wall-viscosity term were considered. The goodness of fit in each case was evaluated. Results: Simulated radial blood pressure was generated using central blood pressure as the input of the proposed 1D tapered model. Results obtained showed an improvement as a consequence of introducing wall viscosity into the model calculations. Discussion: The effect of viscoelasticity has a great significance in the implementation of computational models, since a better fit between simulated and experimental data is achieved.
