This paper is concerned with the computational
results of two-dimensional axisymmetric rigid and elastic wall formulation. In
this paper, steady flow in a stenotic vessel is simulated and compared to
available numerical data with COMSOL Multiphysics software. Numerical results
for a 2D axisymmetric vessel of 45% area reduction indicate that as the area is
reduced with the decreasing of cross-section, the maximum axial velocity at
post stenotic decreases until the end of the artery but the radial velocity
increases upto 4 mm from the stenosis throat and then decreases. Overall,
comparison is carried out on hemodynamics for elastic and rigid wall of steady
flow. Our investigated findings may enable risk factor for patients with
attacked cardiovascular diseases and can play an important role to detect a
solution to such kinds of diseases.
