Abstract

There has been a tremendous progress in most of the computational domains in recent times. One of the key areas is analyzing the complex interaction of blood flow through elastic artery. Such study will aid in predicting the progression and behaviour of diseases like atherosclerosis and hypertension. In the present investigation, a simple straight common carotid artery having an eccentric blockage is analyzed for normal as well as high blood pressure condition. The clinical data has been obtained from ultrasound measurements on a volunteer patient and a model is generated, ANSYS, a commercially available Finite Element Analysis software. The ANSYS Fluid-Structure Interaction (FSI) solver is used to perform the coupled field transient analysis for three pulse cycles and the obtained results demonstrate the pulsatile flow. The simulation shows that the influence of hypertension has high deformation than normal case, severely altering the flow dynamics in downstream of the stenosis. The results obtained agree very well with available clinical observation of normal blood pressure condition.
