Magneto hybrid nanofluid flow with activation energy and chemical reaction through an impermeable stretching elastic cylinder

Abstract

ABSTRACT This article focuses on the study of incompressible, steady, and electrically-conducting hybrid-nanofluid flow through an impermeable stretching elastic cylinder. The base fluid chosen for the study is water and two nanoparticles, namely Cu and graphene, are used for the hybrid nanofluid, while Cu is used for the usual nanofluid. The system takes into account the presence of a chemical reaction, activation energy, and a magnetic field. A comparative analysis is performed to examine the impact of these factors on the hybrid nanofluid and usual nanofluid. The governing equations are transformed into non-dimensional form using similarity transformation and solved using the RK-4 method. The study utilizes graphs and tables to analyse the influence of relevant factors on the flow profile. The results indicate that the temperature decreases with the activation energy factor but increases with the chemical reaction and curvature factors. Both heat and mass transport processes are enhanced by the activation energy parameter, while the opposite effect is observed for the chemical reaction parameter.
