Oblique rotational dynamics of chemically reacting tri-hybridized nanofluids over a suddenly moved plate subject to Hall and ion slip currents, Newtonian heating and mass fluxes

Abstract

The hydro-thermodynamical performance and efficiency of exceedingly sensitive systems is a significant issue in many engineering and scientific processes in the present day. Nanomaterials that have undergone hybridization exhibit novel properties that make them useful in various engineering contexts. Compared to hybridized nanofluid (HNF) and nanofluid (NF), a tri-hybridized nanofluid (THNF) is a novel concept in the field of investigation that provides a more efficient rate of heat transmission. Impelled by these, we quest to explore the dynamism of a non-Newtonian water-ethylene glycol mixture (vol.60–40 %) based tri-hybridized nanofluid (Cu–Ti O2-A l2O3/WEG) on an oblique plate with ramped motion in the attendance of Hall and ion-slip currents, Darcy's porous resistance, heat radiation, chemical reaction, Newtonian heat and mass fluxes in a magneto-rotating environment. The partial differential equations (PDEs) portraying the physical problem are set up via physical hypotheses and constraints. The subsequently obtained non-dimensional PDEs are unsteady, addressed by the Laplace transform method analytically. The physical effects of significant emergent factors, the accompanying flow patterns, and the assessment of industrial relevance are executed and thoroughly explained using a variety of graphics and tables. Our analysis proves a sharp upsurge in the resultant velocity over higher variations of Hall and ion-slip parameters. Increasing estimations of chemical reacting factor and NPs' volume fractions significantly deteriorate the mass transfer rate, while reversal conduct is prevailed due to Newtonian mass flux. Additionally, comparatively lower mass transmission for tri-hybridized nanofluid is documented than hybridized nanofluid. Our modelling could be applicable in industrial processes, dynamics of nano-polymers, hybrid nano-lubricants used in heat management systems, etc.
