Study by Finite Elements of the Fluid-Structural Interaction Between the Carotid Artery and the Blood Flow

Abstract

We did in this work a study about the numerical simulation of the blood flow and the fluid-structural interaction between blood and the carotid artery. The numerical technique used was the finite elements through the software Ansys. The Non-Newtonian behavior of the blood flow was considered and this phenomenon was represented by the Carreau method. Also the turbulence in the blood flow was considered and it was represented by the K-å model. Besides that, the blood with incompressible characteristic was considered. As a boundary condition in the fluid mechanics, the wave produced by the heart in form of periodical pulse was considered, during the systole. For the structural study of the artery deformation, as a boundary condition, the pressure produced by the blood flow was also considered. As a result, the velocity variation, pressure, turbulent kinetic energy, linear pressure and deformation of the artery were showed in 3D in the qualitative and quantitative form. The result of this work was similar to the literature work.
