Impact of Hall current and homogenous–heterogenous reactions on MHD flow of GO-MoS2/water (H2O)-ethylene glycol (C2H6O2) hybrid nanofluid past a vertical stretching surface

Abstract

The need for efficient heating and cooling systems in the automotive, aerospace, and chemical industries is driving the growth of heat transfer technologies. The hybrid nanomaterials are preferred over traditional nanofluids due to their exceptional thermal effectiveness. Keeping in mind the need for efficient cooling and heating systems, the thermal flow model based on the hybrid nanoparticles (GO-MoS2) immersed in hybrid base liquid C 2 H 6 O 2 − H 2 O is presented in this novel attempt by considering the influence of homogeneous–heterogeneous (H–H) reactions and Hall current with a magnetohydrodynamic effect induced by a vertical stretching sheet. A simplified examination is examined in the existence of solar radiation, mixed convection, and viscous dissipation. Suitable transformations provide the system of ordinary differential equations. Later, the solution is tackled numerically for the flow problems using the Runge–Kutta–Fehlberg process with a shooting technique. The role of influential parameters on involved distributions is discussed graphically and is explained logically in view of physical significance. Results reveal that, the thermal profile declines near convectively heated surface and upsurges away from the surface for incline in mixed convection parameter. An upsurge in the Biot number inclines the rate of heat transfer, but a contrary trend can be seen for escalating values of volume fraction.
