Investigation of Arrhenius activation energy and convective heat transfer efficiency in radiative hybrid nanofluid flow

Abstract

The global energy need the development and functioning of heat exchangers and thermal systems for the use and resuscitation of thermal energy. Because of the heat transfer enrichment properties of nanoparticles, industries including nuclear reactors, biological sensing, gas sensing, solar synthesis, the chemical industry, and others have considered using nanoparticles in their respective fields to advance the thermal efficiency of normal liquids. In connection with this, we have envisioned a mathematical model that illustrates the flow and radiative heat transfer of a hybrid nanofluid over a curved stretching sheet with the injection/suction and Arrhenius activation energy. A numerical solution is attained using the Runge–Kutta–Fehlberg fourth, fifth-order and the shooting process. The solution is established through the graphs, which explain each profile in terms of involved parameters. Results reveal that the velocity of the liquid decreases as suction upsurges. The heat transfer enhances for rising values of radiation parameter and Biot number for injection and suction cases. The rate of mass transfer decreases for a rise in values of activation energy parameter, but the differing movement is detected for increasing values of chemical reaction rate parameter.
