Simulating blood flow and oxygen transport in stenosed large arteries
Altered flow and mass transfer patterns are thought to play an important role in the early onset of atherosclerosis. A disturbed wall shear distribution and the prevalence of hypoxic (low oxygen tension) are specifically believed to be atherogenic factors, which can function as a positive feedback on the development of atherosclerosis. In this work, blood flow and oxygen mass transport have bee...
متن کاملMathematical modelling of Sisko fluid flow through a stenosed artery
In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...
متن کاملNumerical simulation of pulsatile turbulent flow in tapering stenosed arteries
Purpose – The purpose of this paper is to investigate the geometric effects and pulsatile characteristics during the stenotic flows in tapering arteries. Design/methodology/approach – The low Reynolds number k ! turbulence model is applied to describe the stenotic flows in the tapering arteries in this paper. The results are divided into two sections. The first section characterizes the geometr...
متن کاملEFFECf OF TI-IENON-NEWTONIAN VISCOSITY OF BLOOD ON STEADY AND PULSATILE FLOW IN STENOSED ARTERIES
The effect of non-Newtonian viscosity of blood on the steady and pulsatile flow in a straight rabbit femoral artery with various degrees of stenosis is investigated numerically using a finite element technique for the peak Reynolds numbers of 65 and 100. The Cross model is used to take into account the non-Newtonian viscosity of blood at various shear rates. The infiniteand zeroshear-rate visco...
متن کاملNumerical Investigation of Angulation Effects in Stenosed Renal Arteries
Background: Numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers.Objective: This paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow.Method: An anatomically realistic model of abdominal aorta and renal arteries is reconstructed from CT-scan images and u...
