VARIATION OF THERMAL CONDUCTIVITY AND HEAT ON MAGNETIC MAXWELL HYBRID NANOFLUID VISCOUS FLOW IN A POROUS SYSTEM WITH HIGHER-ORDER CHEMICAL REACT

Abstract

More demanding applications of nanofluids are of tremendous interest in research and engineering. The implementation of nanotechnology in modern science has prompted researchers to examine nanofluid models from a variety of directions. The current study's major goal is to characterize the impacts of an incompressible, time-independent, viscous, two-dimensional, and laminar Maxwell hybrid nanofluid flow in a porous system under the effect of magnetic field, thermal conductivity, and heat sink/source over a stretching sheet. The hybrid nanofluid is created by immersing various silver and titanium dioxide nanoparticles in a water simple fluid. Additionally, the actions of Joule heating, Maxwell parameter, and higher-order chemical reaction are considered in this model. Within the shooting mechanism, the resulting nonlinear ordinary differential equations are numerically computed utilizing the RKF45 solver given in the computational MATLAB program. It is found that heat and mass transfer are diminished by increasing the magnetic field, Maxwell parameter, and permeability of porous media. Furthermore, an increase in the order of chemical reactions increases mass transfer. Increasing thermal conductivity and heat source/sink increases mass transfer but decreases heat transfer. The created thermal flow model's results have applications in cooling systems, thermal engineering, nuclear heating, heating/cooling of diverse appliances, safety in astronomical equipment, solar problems, magnetic retention, and so on.
