CFD Simulation of Steady Blood Flow through Left Subclavian Stenosed Artery, Turbulence Modeling and Critical Narrowing
Journal Title: JOURNAL OF ADVANCED RESEARCH IN APPLIED MECHANICS & COMPUTATIONAL FLUID DYNAMICS - Year 2017, Vol 4, Issue 3
Abstract
In this work, we first propose a precise geometry for any arterial stenosis. Then we use the CFX-ICEM-ANSYS 15.0 code to perform a computational simulation of blood flow in the aortic arch, both in the healthy case and in the case of presence of stenosis in the left sub-clavian artery with various stenosis degrees. Then, we discuss our results obtained for the main hemodynamic parameters (velocity, pressure, wall shear stress) and compare them with those obtained from medical imaging and numerical studies. We also study the turbulent effects, via a modeling of the Reynolds number in function of stenosis degree, the length of recirculation zone and the critical narrowing.
