A study of thermal conductivity enhancement in magnetic blood flow: Applications of medical engineering

Abstract

Although human tissues already have blood-based temperature regulation, nanofluids can make this process even more powerful. In this study, we aim to examine the flow of a hybrid nanoliquid, consisting of the Yamda-Ota (Y-O) and Hamilton-Crosser (H-C) models, through an inclined magnetic field, past a horizontally extending sheet, including silver and gold nanoparticle, with blood as the base liquid. Heat transport, homogeneous-heterogeneous (homo-hetero) reactions, and magneto-hydrodynamic (MHD) effects are all taken into consideration. Heat generation and absorption, temperature stratification, and linear radiation are all taken into account. The second law of thermodynamics is used to conduct an analysis of irreversibility. Also examined are the effects of stratification, as well as heat sources and sinks with varying thermal conductivity. Numerical solutions to the mathematical model are found using the bvp4c package in MATLAB. As a means of presenting and analyzing the results, tables and figures are employed. As you change the parameters, you can see the force coefficient graphically. The outcomes demonstrate that, when comparing the two models, the Y-O approach to introducing hybrid nanofluid (HNF) flow is more advantageous. The results show that an augmentation in the nanomaterial volume fraction $({\varphi }_1,{\varphi }_2)$ decline the velocity profile.
