Objective: To set up a model of pulse wave propagation in a curved artery and compare the differences of pulse wave propagation between straight and curved arteries Methodology: In previous work, we deal with a three-segment wave propagation model in a straight tube. In this paper, as a follow up study, we construct a wave propagation model in a curved artery based on the three-segment model developed in a straight tube. Numerical simulation is performed using a fluid-structure interaction Findings: The comparison of this curved model and previous straight model indicates that arterial geometry has a significant impact on pulse wave propagation. An obvious time delay occurs whether between the peaks or between the bottoms in a straight tube. However, the time delay only occurs between the bottoms in a curved artery while it does not clearly exist between the peaks. The finding indicates that a time delay between bottoms is more stable and easy to catch. Actually, a velocity wave is just quantized by usually measuring a time delay between bottoms in clinics and experiments. Modeling of pulse wave propagation in a curved artery and the use of wave propagation model can be better made to perform hemodynamic distributions and predict vascular disorders.
