Analisis Output Model Aliran Darah Arteri Brakialis Menggunakan Model Fluida Casson

Abstract

Blood flow modeling is a crucial area of research in medicine and biomedical engineering. This study aims to analyze the output of a blood flow model in the brachial artery, specifically using the Casson fluid model. Parameters such as flow velocity, pressure distribution, velocity gradient, and external forces will be evaluated to understand the characteristics of blood flow under normal conditions. This research is expected to provide valuable insights into the behavior of arterial blood flow, particularly in the brachial artery. The blood flow model employed includes three equations: the continuity equation, the momentum equation, and the Casson fluid model. The finite volume method (FVM) will be used to implement these equations in the software. In this study, three stenosis scenarios in the artery were simulated, namely 40%, 50%, and 60%. The simulation results show that the blood flow velocity in the artery is inversely proportional to the blood flow pressure. The blood flow velocity increased and reached its peak at 60% stenosis, while the blood pressure decreased with the lowest pressure at 60% stenosis, indicating the highest stability at 40% stenosis for both parameters.
