Understanding blood flow dynamics within the intricate network of blood vessels is crucial for advancing medical diagnostics and interventions. Computational methods, particularly Computational Fluid Dynamics (CFD), have emerged as powerful tools for studying blood flow behavior, offering invaluable insights into hemodynamic parameters and various physiological conditions. However, the utility of computational simulations in clinical decision-making relies on their accuracy and reliability, necessitating rigorous validation. In this paper, we describe a method of validating shear stress simulation on blood vessel walls by comparing it with a physical erosive model. The parametric arterial model was created in ANSYS, using morphometric parameters obtained from Murray's law. The model was simulated with non-Newtonian blood properties and a constant velocity. A physical model was created using 3D printing and tested under similar flow conditions. Results show agreement between simulated and physical models, confirming the efficacy of computational simulations in understanding vascular physiology and pathology. This underscores the need for continued validation and refinement to maximize their clinical utility.
