Radiative MHD flow and heat transfer characteristics of Cu-Fe3O4 /blood base hybridized nanofluid through stenotic artery

The main purpose of the present study is to examine the key role of Cu and Fe3O4 nanoparticles that are submerged in human blood in the existence of magnetohydrodynamics (MHD) flow through the stenosis artery. The reason behind the selection of Cu and Fe3O4 nanoparticles is that they show high potential usefulness in drug delivery and imaging properties. Moreover, the governing partial differential equations (PDEs) that define the flow and the heat transfer characteristics of blood-based hybrid nanofluid (HNF) are converted to non-dimensional form of ordinary differential equations (ODEs) using suitable similarity transformation. The shooting method is applied to solve the equations through Maple software to observe the effects of specified nanoparticles volume fractions and used physical parameters in stenotic arteries. The results show that the velocity of human blood gradually decreases with an increase in the size of the nanoparticles but temperature increases in both cases of the , either stretching or shrinking. Moreover, an increase in magnetic, suction/injection, and nanoparticle volume fractions decrease the velocity of the blood-based hybrid nanofluid flow through the stenotic artery. While, an increase in thermal radiation, magnetic, flow parameters, and nanoparticle volume fraction increases the temperature of the blood during flow through the stenotic artery. On the other hand, the Prandtl number and suction/injection parameter decrease the temperature of the blood during flow through the stenotic artery. The present research has the potential that be proven highly advantageous for an effective drug delivery in human blood arteries.
