Hydrothermal analysis on non-Newtonian nanofluid flow of blood through porous vessels

Abstract

In this paper, the flow of non-Newtonian blood fluid with nanoparticles inside a vessel with a porous wall in presence of a magnetic field have been investigated. This study aimed to investigate various parameters such as magnetic field and porosity on velocity, temperature, and concentration profiles. In this research, three different models (Vogel, Reynolds and Constant) for viscosity have been used as an innovation. The governing equations are solved by Akbari-Ganji's Method (AGM) analytical method and the Finite Element Method (FEM) is used to better represent the phenomena in the vessel. The results show that increasing the Gr number, porosity and negative pressure increase the blood velocity and increasing the magnetic field intensity decrease the blood velocity.

Hemodynamics and Wall Shear Stress of Blood Vessels in Aortic Coarctation with Computational Fluid Dynamics Simulation

“…Sud and Sekhon [34] presented a mathematical model for flow in single arteries subject to a pulsatile pressure gradient as well as the body acceleration. In their analytical treatment, blood was assumed to be a Newtonian fluid and flow as laminar and one dimensional; and the tube wall was assumed to be rigid and uniformly circular [34][35][36]. A fully developed flow was given as an inlet condition to analyze the characteristic of the blood flow within the blood vessels in which the stenosis occurred; numerical analysis with the velocity distribution of the Reynolds numbers (Re) of 500, 800, and 1200 at the inlet was carried out.…”

Comparative simulation of nonlinear radiative nano casson and maxwell fluids with periodic magnetic force and sensitivity analysis

“…Due to the fact that a specific fluid model did not calculate all of the non-Newtonian fluids' physical characteristics so in different times a lot of scholars recommended various non-Newtonian fluids models [ 15 , 16 ]. Such as, a power-law non-Newtonian fluid in deformable, fractured porous media was investigated by Hageman et al [ 17 ]. Mustafa et al [ 18 ] quantitatively evaluated the effects of a helical absorber tube on the thermal efficiency of a solar collector (PTSC) filled with non-Newtonian nanofluid.…”

A numerical solution using EFDM for unsteady MHD radiative Casson nanofluid flow over a porous stretching sheet with stability analysis

“…Khan et al 10 12 did a numerical study of how well heat moves through a threedimensional MHD ferrofluid across a sheet that was stretching in both directions exponentially. Hosseinzadeh et al 13 investigated the flow of non-Newtonian nanofluid of blood inside a porous vessel in the presence of a magnetic field. Due to enormous practical applications, researchers are nowadays interested in surfacedriven flows.…”
