Comparative analysis between copper ethylene-glycol and copper-iron oxide ethylene-glycol nanoparticles both experiencing Coriolis force, velocity and temperature jump

Abstract

Sequel to the industrial usage of ethylene-glycol conveying copper nanoparticles, nothing is known on how the dynamics differ from ethylene-glycol conveying copper and iron oxide nanoparticles when there is Coriolis force, slip and thermal jump. This report presents the outcome of a study on the motion and heat transfer across both non-Newtonian electro-conducting Carreau hybridized nanofluids via the porous medium on a three-dimensional rotating stretchable plate. The model for hybridization of the mixture of copper (Cu) and Iron oxide (Fe3O4) nanoparticles in the ethylene-glycol base fluid under thermal radiation, uneven heat source and wall slip attributes were developed and presented. The reduction of the model equations from partial into ordinary differential equations was carried out using similarity transformation variables. Pseudo-Spectral Method (PSM) was employed to solve the emerged boundary value problem. Exponential space-based heat source/sink, stretching rates, and temperature jump levels, heat transfer rates are maximal during ethylene-glycol conveying copper nanoparticles but minimal during ethylene-glycol motion conveying copper and iron oxide nanoparticles. The hybridization of the nanoparticles induces a higher heat propagation than the unitary nanofluid for all the physical parameters considered, whereas the strength of the surface drag force depreciates with a higher magnitude of the Weissenberg number.
