Mathematical and computational fluid dynamics modeling of non-Newtonian blood flow demonstrated that wall shear stress and flow distribution are significantly affected by increasing stenosis severity.
How does increasing severity of stenosis affect wall shear stress and flow distribution in a non-Newtonian blood flow model?
Mathematical and CFD modeling of non-Newtonian blood flow through stenotic arteries demonstrates significant alterations in wall shear stress and flow distribution with increasing stenosis severity.
AbstractThis study employs mathematical and computational flow modeling to discern the blood flow through a stenotic artery and improve the understanding of hemodynamics in pathological situations. To assess blood flow realistically through the stenosed parts of the artery, blood is modeled as a non-Newtonian fluid. The governing motion equations in cylindrical coordinates are solved and, the velocity, temperature, and concentration fields are generated and illustrated in a graph showing the effects of several dimensionless parameters, including the Grash of and Brownian motion parameters. The results indicate that the wall shear stress and flow distribution are significantly affected by the increasing severity of stenosis. The results of the Computational Fluid Dynamics (CFD) model are validated against existing analytical solutions, which are in close agreement. Wall stress and effective resistance blood flow results elucidate the clinical diagnostic and therapeutic process flow for patients with cardiovascular disease (CVD).
