COMPUTER SIMULATION OF BLOOD FLOW IN ARTERIES AFFECTED BY MULTIPLE ANEURYSM

The aim of this study is a numerical simulation of hemodynamics in blood vessels with multiple fusiform aneurysms. Dilation of 0.25 is considered. Using computational fluid dynamics, hemodynamic factors such as velocity and pressure are investigated. The problem is solved by finite volume method. Numerical simulation is prescribed using the CFD softwares Fluent and Gambit. High pressure and low velocity is observed in the region of aneurysm. This is an indication to the interruption of blood flow. These techniques based on computer flow study are important for understanding the relationship between hemodynamic parameters and risk of rupture.
