Synergistic thermal and magnetic influences on non-Newtonian hybrid Casson nanoblood flow in arterioles

Abstract

Analyzing blood flow patterns plays a pivotal role in diagnosing circulatory disorders, including arteriosclerosis. This significance has driven bio-engineers and medical researchers to concentrate on understanding the dynamics of blood flow within the circulatory system. In this context, we examined the Hall and ion slip effects on non-Newtonian Casson blood flow in arterioles, driven by a radial magnetic field. Additionally, this study explores the momentum and heat transfer characteristics of non-Newtonian blood infused with hybrid magnetic and semiconductor nanoparticles, accounting for the impacts of viscous dissipation and Joule heating phenomena. The current model of blood flow with hybrid nanoparticles through an arteriole is represented mathematically by a system of partial differential equations, which was transformed into dimensionless form and solved using two distinct numerical techniques to ensure the reliability of the results. The main outcomes of this study indicate that as the Hall parameter increased from m=0.2 to m=1.0, the axial velocity and temperature at the center of blood arterioles significantly improved by 37.98% and 75.31%, respectively. Moreover, hybrid nanoparticles are more effective at regulating blood flow and temperature compared to mono nanoparticles, which further enhancement possible by increasing the concentration of magnetite nanoparticles in the mixture. Additionally, higher values of the Casson fluid parameter enhanced the velocity and temperature of hybrid nanoblood. The findings of this research present significant potential for applications in targeted drug delivery, magnetic therapy, therapeutic hyperthermia treatments, thermal energy transfer, and biomedical sensors.
