Reproduction of Pressure Wave Propagation in the Abdominal Aorta using a Hemodynamic-based 1-D Flow Model

Human blood pressure is influenced by various factors in the arterial system, including arterial stiffness, wall thickness, cardiovascular diseases, heart rate, and cardiac output. When blood pressure propagates from the central aorta to peripheral arteries, the pulse pressure magnitude and waveform change. Understanding the pulse propagation mechanism in arteries can aid in the diagnosis and treatment of cardiovascular diseases. In this study, we modeled the human aorta using hemodynamic equations, assuming incompressible Newtonian blood and simplified cylindrical arterial vessels. Our model accurately represented the length and properties of the human aorta, including the ascending aorta, iliac arteries, and aortic bifurcation. Comparing the simulation results with cardiovascular hardware experiments, we confirmed the matching trends in pressure pulse wave propagation.
