This model examines the variable thermal conductivity, variable molecular diffusivity, and Arrhenius activation energy in the elliptical stenosis configuration within an artery containing tetra-hybrid nanoparticles (gold, copper oxide, graphene oxide, titanium oxide). The governing partial differential equations, such as those for continuity, microorganisms, momentum, temperature, and concentration, are determined based on the physical boundary and initial conditions. These are subsequently transformed into dimensionless quantities by utilizing the assumed moderate stenosis, defined as a maximum height considerably less than the artery’s radius, with the length of the stenotic zone proportionate to the artery’s radius denoted as ε=O(1). The graphical depiction of the diverse profiles utilizing the explicit FTCS technique ultimately reveals the conclusion that the wall shear stress rises when the depth of stenosis is enhanced, while the Nusselt number diminishes at the arterial wall. The reducing velocity and volumetric flow rate follow from a change in the magnetic field parameter. By contrast, a rise in the heat source parameter raises the temperature profile. The use of individual nanoparticles, including copper oxide nanoparticles, titanium oxide nanoparticles, graphene oxide nanoparticles, and gold nanoparticles, has shown a decrease in lipid build-up in cardiovascular disease treatment by raising blood temperature. This initiative shows potential for the progression of biomedical device design. It provides significant insights into hemodynamic flow, applicable therapeutically in the biological sciences.
