Simulation of Hemodynamics Phenomenon Using Computational Fluid Dynamics for Enhanced Diagnostics and Prognosis

Abstract

Computational bio-mechanics is developing rapidly as a non-invasive tool to assist the medical fraternity to help both diagnosis and prognosis of human body related issues such as injuries, cardio-vascular dysfunction, atherosclerotic plaque etc. Any system that would help either assist diagnosis prognosis would be a boon to the doctors and medical society in general. Some work also has been done in the area related to the use of computational fluid mechanics to understand the flow of blood through the human body, an area of hemodynamics. Since cardio-vascular diseases are one of the main causes of loss of life, understanding of the blood flow with and without constraints (such as blockages), providing alternate methods of prognosis and further solutions to take care of issues related to blood flow would help save valuable life of such patients. This work attempts to use computational fluid dynamics (CFD) to solve specific problems related to hemodynamics. In particular mathematical modeling of the blood flow in arteries in the presence of successive blockages has been analyzed using CFD. Also considered is the effect of increase in Reynolds number on wall shear stress values. Also, the concept of fluid structure interaction has been used during analysis. � 2015 IEEE.
