摘要

The study of blood flow in a narrow blood vessel, particularly under the influence of metallic and non-metallic nanomaterials, has gained significant attention due to its rheological complexities and practical biomedical applications. This research holds profound implications for diverse fields such as drug delivery systems, cancer treatment, thermal therapies, blood filtration technologies and microcirculation studies. In this context, a computational framework has been developed to investigate hemodynamic properties within a blood stream by infusing magnetite, gold and copper nanoparticles, which serve as drug delivery agents. These nanoparticles facilitate targeted drug delivery, enhance thermal therapies through improved heat transfer and contribute to real-time imaging and antimicrobial applications, thereby advancing medical technological innovations. The proposed model employs a couple stress fluid formulation to capture the interactions between blood and nanomaterials, effectively representing the non-Newtonian behavior of blood in narrowed vessels. To enhance the realism of the study, critical effects such as radiation, magnetohydrodynamics (MHD), viscous dissipation and heat source influence are incorporated. The governing equations are numerically solved using the spectral collocation method and results are presented through comprehensive graphical representations. These results highlight thermal and velocity distributions within the bloodstream, showing that an elevation in magnetic field strength, wall deformation, and couple stress parameters results in a retardation of blood flow velocity due to resistive forces. The findings demonstrate that ternary nanofluids comprising magnetite, copper, and gold nanoparticles exhibit superior thermal and flow performance compared to hybrid and simple nanofluids. Additionally, the study provides insights into the design of advanced medical devices, including bioengineered tissues and dialysis systems, where precise control of fluid dynamics and heat transfer is essential.
