Numerical investigation of blood flow through abdominal aneurysms

Cardiovascular diseases are very common in today’s world. It is of great importance to simulate the behavior of arteries subjected to various anomalies using computational methods, as it will help the clinicians in the early diagnoses of the disease. This paper enumerates the use of computational fluid dynamics (CFD), for simulating blood flow phenomenon in human arteries, especially Abdominal Aortic Aneurysm (AAA). The use of the CFD in simulating the anatomically realistic models is discussed. Different methodologies applied for assessing the effectiveness in predicting the behavior of blood flow in arteries is presented. In this study, it was observed that higher wall shear stress is observed at peak systole. It reduces at early diastole which leads to flow separation and recirculation inside the aneurysm dome.
