Computational analysis for magnetized radiative Jeffrey nanofluid (Au/ C2H6O2) flow in a rotating system with activation energy

Abstract

The current paper is aimed at investigating the impact of Arrhenius energy and thermal radiation on a Jeffrey nanoliquid using the Tiwari-Das model within a rotating porous system. The study includes Au, (Gold) as a nanoparticle, and ethylene glycol (EG) as a base fluid. The leading partial differential equations describing the flow are formulated based on the general laws of momentum, energy and species concentrations. The applicable dimensionless configuration reduces the complexity of the flow model, allowing it to be solved numerically. The Runge-Kutte Fehlberg scheme, in concert with MATLAB, is used to solve the transformed equations. Multiple graphs and tables are used to examine the new results comprehensively regarding fundamental flow, magnetic, and thermal properties for various implanted parameters. It is observed that the concentration profile seems higher for progressive values of Arrhenius energy, whereas the opposite behaviour has been observed for greater values of the Schmidt number and chemical reaction parameter. The findings from this research can be applied to the development of many technologies such as solar power plants, nanofluidic devices, micro pumps, etc.
