Abstract
The higher-order rate of reactions of spinning [PEG-H2O/ZrO2](m) mono, and [PEG-H2O/ZrO2+MgO](h) hybrid nanofluid on an expanding surface is taken into account in the present investigation. The non-linear flow terms are numerically resolved with Runge-Kutta-Fehlberg of 4-5th order (RKF45) technique. In comparison, the mono and hybrid nanofluids are addressed as enhanced heat transport. It is found that with 1% [MgO](NPs), the thermal conductivity increases by 69.6%. [PEG-H2O/ZrO2+MgO](h) enhances the heat transmit rate than [PEG-H2O/ZrO2](m). The nanostructure thin films of [PEG-H2O/ZrO2](m) and [PEG-H2O/ZrO2+MgO](h) are fabricated by utilizing a spin coating process with a thickness of 200 +/- 5 nm/25 degrees C. The nanofluid thin films are studied using combined experimental and theoretical method (DFT density function theory), including FT-IR (Fourier-transform infrared) spectrum. The results specifically determine that Delta E-g(Opt) (difference energy bandgap) values decrease from 2.294 eV for [PEG-H2O/ZrO2](m) to 0.677 eV for [PEG-H2O/ZrO2+MgO](h) using the DFT computations. This result concluded that the [PEG-H2O/ZrO2](m) transformed from semiconductor to [PEG-H2O/ZrO2+MgO](h) as a superconductor hybrid nanofluid by addition (MgO nanoparticles).
