Computational framework on heat diffusion in blood-based hybrid nanoliquid flow through a stenosed artery: An aligned magnetic field application

Abstract

The silver and gold nanoparticles display noteworthy results in antimicrobial and anticancer therapies. Silver is a considerable anti-inflammation, and gold nanoparticles effectively use to convert the photons to heat to destroy cancer cells. By keeping this in view, we investigated the radiative heat allocation in blood-based Ag-Au hybrid nanofluid flow. We assumed a blood vessel with cosine stenosis in the existence of an aligned magnetic field and variable heat source/sink. The flow model was developed to investigate the underlying physics and solved numerically after applying appropriate transformations. The computational outcomes for the flow and energy fields were explored through graphical and numerical illustrations. Also, the consequences of local Nusselt number and wall friction were discussed. The outcomes are validated and found to be in noble agreement. It is noticed that the inclined magnetic angle can control the drag force and heat transmission. Also, the Ag-Au combination effectively enhances the rate of heat transfer. This may help the effective conversion of photons to heat energy used in cancer therapies.
