Simulation of Physiological Non-Newtonian Blood Flow through 3-D Geometry of Carotid Artery with Stenosis
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
A numerical simulation has been performed to investigate blood flow behavior of three dimensional idealized carotid arteries. Non-Newtonian flow has been taken for the simulation. The wall of the vessel is considered to be rigid. Physiological and parabolic velocity profile has been imposed for inlet boundary condition. Reynolds number at the inlet has been ranged approximately from 86 to 966 for the investigation. Low Reynolds number k-w model has been used as governing equation. The investigations have been carried out to characterize the flow behavior of blood. The numerical results have been presented in terms of wall shear stress distributions, streamlines contours and axial velocity contours. However, highest wall shear stress has been observed in the bifurcation area. Unexpectedly, transient or unstable flow has created flow disturbance regions in the arteries. Moreover, the disturbance of flow has risen as the severity of stenosis in the artery has been increased.
