Revealing the Hemodynamic Orchestra: Contrasting Analysis of Blood Flow Patterns in a Bifurcated Carotid Artery
Abstract: Understanding blood flow patterns in the carotid artery (CA) is crucial for detecting cardiovascular diseases. Computational fluid dynamics simulations compared non-Newtonian (non-Newt) and Newtonian (Newt) models under pulsatile and laminar flow. CA geometry was accurately designed using ANSYS Space Claim & Fusion360, and simulations were run in ANSYS Fluent. Discrepancies between non-Newt and Newt models were found, especially in bifurcation's distal regions prone to plaque. Pressure ranged from 27.870 Pa …

DEM Simulation of Macro and Micro-scale Behavior of Granular Materials during Loading and Unloading
Abstract: The present paper aims at comparing the simulated stress-strain behavior of granular materials quantitatively with the experiment and exploring the evolution of the micro-scale behaviors during loading and unloading using the discrete element method (DEM). A numerical sample consisting of 9826 randomly generated spheres similar to the experiment was prepared. The numerically prepared isotropic sample was subjected to loading and unloading under strain controlled condition. It is noticed that the …
