Research ArticleOpen accessIn the keywordsFlow Characteristics in Elastic Arteries Using a Fluid-Structure Interaction ModelH. Niroomand Oscuii, M. Tafazzoli Shadpour, Farzan GhalichiIn this study the interaction of blood flow with arterial wall has been investigated using FSI (Fluid-Structure Interaction) modeling. Computer simulation of pulsatile blood flow was carried out on the basis of the time dependent axisymmetric Navier-Stokes equations for an incompressible Newtonian fluid flow. An elastic incompressible material with large deformation was considered for the arterial wall and momentum and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,429 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSOLITARY WAVE MODULATION IN AN ARTERY WITH STENOSIS FILLED WITH A VISCOUS FLUIDYaan Yee Choy, Kim Gaik Tay, Chee Tiong OngIn this study, the derivation of mathematical model for the wave modulation through an incompressible viscous fluid contained in a prestressed thin stenosed elastic tube is presented. The artery is assumed to be incompressible, prestressed thin walled elastic tube with a symmetrical stenosis, whereas the blood is considered to be incompressible and Newtonian fluid. By utilizing the nonlinear equations of … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 4 Sep 2013 · 7,085 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New System to Analyze Pulsatile Flow Characteristics in Elastic Tubes for Hemodynamic ApplicationsAfshin Anssari-Benam, Mohammad Tafazzoli-Shadpour, Nasser Fatouraee et al.In this research, we present a new designed experimental setup for study of characteristics of pulsatile flow in elastic tubes, aiming to simulate arterial blood flow. This system includes four major components: (1) a pulsatile pump producing original arterial flow, (2) an elastic element to simulate coupling of the heart with the arterial system, (3) an elastic tube with mechanical … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,009 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamic Stress Analysis of the Arterial Wall Utilizing Physiological Pressure WaveformsM.M. Khani, M. Tafazzoli-Shadpour, S. Delavarpour et al.Arterial diseases, promoted by alterations in arterial wall properties, are among the main causes of mortality. Mechanical stresses of the arterial wall caused by pulsatile luminal pressure define arterial function in normal and pathological conditions. This study aims to determine dynamic stress distribution in the arterial wall subjected to physiological pressure waveforms. Finite element models of a typical artery are … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,163 accessesView PDF Cite
