A modified thermal flux model to examine the enhanced heat transmission in hybrid blood flow through artery: A comparison between Maxwell and Oldroyd-B models

Nanotechnology assists high-class openings for biomedical purposes, which could impact medicine and health-related challenges. This technology benefits in many aspects, such as nanocarrier for targeted drug delivery, improved medical imaging, treatment of targeted tumors, and vaccination. Laboratory experiments show that with the help of nanoelectronic devices, the current treatment processes are improving effectively. The outstanding antimicrobial and biocompatibility properties of graphene oxide (GO) and aluminium oxide (Al2O3) nanoparticles are helpful in nano-drug delivery and cancer treatment. In this article, a theoretical investigation is made to examine the heat transfer in GO-Al2O3 suspended blood flow through the stenotic artery. The 2D hybrid blood flow has radiative heat, uniform magnetic field, dissipative, and Cattaneo–Christov thermal flux effects. The comparison of Maxwell and Oldroyd-B hybrid nano models is deemed to analyze the viscoelastic nature of the blood. Altered governing equations are resolved by employing the Keller-Box scheme. Comparative results for Maxwell and Oldroyd-B models are obtained and shown graphically. The outcomes of this study show that the flow of GO-Al2O3 suspended blood under the Oldroyd-B model gives an improved heat transmission rate compared with the Maxwell model. Also, drug resistance is low in Oldroyd-B flow. The properties of GO-Al2O3 nanoparticle composition with the Oldroyd-B rheological nature may help drug delivery.
