Entropy and stability analysis on blood flow with nanoparticles through a stenosed artery having permeable walls

Abstract

In this research, the electro-osmotic effects are highlighted for a blood-based hybrid nanofluid flow across an artery infected with multiple stenosis. The artery has permeable walls together with slip boundary effects. The slip and permeable boundary conditions model the more realistic blood flow problems. The governing equations of the problem are converted into non-dimensional form by introducing adequate dimensionless variables and acquired the exact solutions. The detailed study of heat transfer is given by Joule heating and viscous dissipation effects. The disorder of fluid flow is investigated by the mathematical study of entropy generation. Analytically attained solutions are examined graphically for both symmetric and non-symmetric shapes of stenosis. Streamlines are analyzed for varying values of flow rate Q and electro-osmotic parameter m. The flow velocity has smallest values on the axis of channel and gets higher value near the boundary walls. The temperature profile delineates opposite behavior to the velocity, and it is parabolic in nature. The velocity reduces towards the non-uniform stenosis except for electroosmotic parameter m. The temperature has larger magnitude in the case of anti-symmetric stenosis. Moreover, the stability of velocity solution is also analyzed.

An approach for computational blood flow under the joint effects of the electro-osmotic, magnetic field, chemical reaction and porosity

“…Abdelwahab et al (2021) used a finite difference method for solving blood flow problem where the blood flow is considered as a micropolar incompressible fluid with mass and heat transfer under the effect of electromagnetic and electro-osmotic forces through an artery that has aneurysms and stenosis. Shahzad et al (2022) studied the electro-osmotic effects of a blood-based hybrid nano-fluid flow through an artery with multiple stenoses. The achieved solutions are graphically analyzed for both symmetric and non-symmetric forms of stenosis.…”

Hall and ion slip effects on hybrid nanoparticles (Au-GO/blood) flow through a catheterized stenosed artery with thrombosis

“…They investigated the nanofluid's velocity, impedance, and wall shear stress distribution using the perturbation approximation method with the variant curvature parameter. Shahzad et al 16 developed a mathematical model to study the effect of entropy generation on the stenosis artery with permeable walls having single-wall and multiple-wall carbon nanotubes inside the blood (base fluid). Gandhi et al 17 considered the bell-shaped artery to explore the effect of hybrid nanoparticles (Au-Al 2 O 3 ) on the blood flow subject to temperature-dependent viscosity.…”
