Thermal enhancement and numerical solution of blood nanofluid flow through stenotic artery

Abstract

The blood flow through stenotic artery is one of the important research area in computational fluid mechanics due to its application in biomedicine. Aim of this research work is to investigate the impact of nanoparticles on the characteristics of human blood flow in a stenosed blood artery. In under consideration problem Newtonian fluid is assumed as human blood. Newtonian fluid flows through large blood vessels (more than 300 μm). The constitutive equations together with the boundary conditions are diminished to non-dimensional form by using boundary layer approximation and similarity transfiguration to attain the solution of velocity and temperature distribution of blood flow through arterial stenosis numerically with the help of Matlab bvp4c. The results for physical quantities at cylindrical surface are calculated and their effects are also presented through tables. The heat transfer rate increases throughout the stenosed artery with the concentration of copper nanoparticle. Velocity curve decreases by increasing the values of flow parameter and nanoparticle volume fraction. Temperature curve increases due to increase in the values of nanoparticle volume fraction and decrease in Prandtl number.

Effect of an inclined magnetic field on unsteady mixed convective stagnation point flow over a permeable stretching sheet with radiative heat transfer

“…• The enhancement of the radiative heat ( ) R d and Eckert number ( ) Ec contributes to an increase in the estimation of energy ( ) q h and thickens the thermal boundary layer. Finally, the current findings support with the observed outcomes and are relevant in practice topics such as, jets flow, medicine, chemically engineering, and pharmacology [26][27][28][29][30].…”

MHD flow of the novel quadruple hybrid nanofluid model in a stenosis artery with porous walls and thermal radiation: A Sisko model‐based analysis

“…Many studies have dealt with the study of blood flow in narrow and dilated arteries [18][19][20][21]. In recent years, there has been growing interest in the use of nanoparticles to improve blood flow in stenosis arteries [22][23][24]. Studying of nanoparticles in blood flow through stenotic arteries has focused on developing innovative approaches to improve the delivery of therapeutic agents and address the underlying causes of reduced blood flow in these narrowed blood vessels.…”

Unsteady natural convection flow of blood Casson nanofluid (Au) in a cylinder: nano-cryosurgery applications

“…They obtained the same result as Noranuar et al 38 for the blood temperature but oppositely for the blood velocity due to the heat conductivity and density factors of carbon nanotubes. Sarwar et al 41 explored the behaviour of blood flow as the Newtonian fluid with the dispersion of copper nanoparticles in the arteries. They solved the problem numerically and concluded that nanoparticle causes blood flow and temperature increase.…”
