Numerical study of enhancement of heat and mass transport in the flow of power-law hybrid nano liquid under chemical reaction

Ethylene glycol with nanoparticles behaves as a non-Newtonian fluid and its rheology can be best described by the power-law rheological model. Further, hybrid nanoparticles are responsible for anti-oxidation, anti-evaporation, and anti-aging. Therefore, their dispersion in ethylene glycol is considered as these properties make the nanofluid stable. This article examines the impact of hybrid nanoparticles on the thermal enhancement of ethylene glycol as it is a worldwide used coolant. Moreover, simultaneous effects of temperature and concentration gradients, Joule heating, viscous dissipation, thermal radiations, and Bouncy forces are modeled and models are solved numerically using the finite element method (FEM). An increase in temperature due to composition gradient and an increase in concentration due to temperature gradient are observed. A significant increase in the Ohmic phenomenon with an increase in the intensity of the magnetic field is observed. The thermal performance of ethylene glycol is much improved due to simultaneous dispersion of hybrid nanoparticles relative to the thermal performance of ethylene glycol with mono nanoparticles only.
