Combined experimental thin film, DFT-TDDFT computational study, flow and heat transfer in [PG-MoS₂/ZrO₂]^C hybrid nanofluid

Abstract

Doped [ZrO₂]^NPs in the [PG-MoS₂]^C matrix to fabricated the [PG-MoS₂/ZrO₂]^C hybrid nanofluid films by a sol–gel method, the average crystallite size increased from 66.75 nm to 93.36 nm. The key aim of this article is to investigate the structure, simulated calculations, flow, and heat nanofluid transport in the existence of viscosity and thermal conductivity based on temperature. To make an overall integration between the theoretical and experimental study of selected mono and hybrid nanofluids. Different experimental characterization techniques for the [PG-MoS₂]^C and [PG-MoS₂/ZrO₂]^C hybrid nanofluid films such as UV-Vis, FT-IR, XRD, DFT calculations, and optical characteristics have been used. The most important aspects of this study include that hybrid nanofluid flow is enhanced for increasing values of both ${\phi }_1$ and ${\phi }_2$. The presence convective conditions decelerate the mixture temperature. Lowermost skin friction occurs for 25 vol% of MoS₂: 75 vol% ZrO₂ and ${\phi }_1$ and ${\phi }_2$ lead to an improvement in the heat transport rate. Besides, an increment of ZrO₂ nanoparticles is essential for enhancement. The results specifically demonstrate that the optical energy band difference values from [PG-MoS₂]^C to [PG-MoS₂/ZrO₂]^C decrease with 8.42%.
