Abstract
Modern studies have focused on blood circulation in diseased arteries and nanoparticle dispersion under non-dimensional conditions. This study explores the complex interactions of electro-magnetohydrodynamics in the human circulatory system. We carefully examine the physical characteristics, focusing on the intriguing interaction of forces. We focus primarily on the distinct effects of electroosmotic pressures on a sick arterial segment that is characterised by stenosis along its boundaries. Additionally, this study aims to provide an extensive overview of the impact of heat radiation and the Hall effect on blood flow in stenosed arteries through Williamson hybrid nanofluid. Hybrid nanoparticles can improve heat transfer by increasing thermal conductivity, and they can also modify fluid viscosity, allowing for better control over the flow characteristics. The Williamson nano-fluid model simulates narrow artery blood flow with non-Newtonian properties. Furthermore, the present study investigates the combined effects of consistent and varying (Cu and Cu-CuO/blood) transport in convective processes. The mathematical examination is performed by formulating the physical problem using the Cu and Cu-CuO/blood interactions framework. We solve the governing equation using bvp4c techniques in the mathematical model, along with appropriate boundary conditions. The findings indicate that the axial velocity diminishes with an increase in the Froude and Reynolds numbers. The hybrid nanofluid exhibits superior axial velocity values compared to the nanofluid. The artery aligned horizontally (í µí»¼ = 0) exhibits the slowest axial velocity, whereas the artery oriented vertically (í µí»¼ = í µí¼/2) displays the highest axial velocity. To effectively lower the hemodynamic consequences associated with stenotic arteries, the administration of Cu and Cu-CuO/blood is a more suitable strategy, as demonstrated by the graphical patterns. Hybrid nanofluids (Cu-CuO/blood) exhibit better heat transfer rates than nanofluids (Cu/blood) when the heat source and thermal radiation increase. This approach demonstrates its potential for increased cardiovascular therapeutic interventions. Electroosmosis principles are utilised in devices such as electrophoresis to effectively separate biomolecules. Understanding arterial blood flow is crucial for imaging modalities such as Doppler ultrasonography and MRI.
