An Experimental Study of ZrO₂‐CeO₂ Hybrid Nanofluid and Response Surface Methodology for the Prediction of Heat Transfer Performance: The New Correlations

Abstract

This article experimentally and statistically reports the convective heat transfer performance of a cylindrical mesh-type heat pipe apparatus filled with ZrO2-CeO2/water-ethylene glycol nanofluids. In this regard, ZrO2-CeO2 nanoparticles were synthesized and characterized through the Scanning Electron Microscope and Powder X-ray diffraction methods followed by the preparation of hybrid ZrO2-CeO2 nanofluids of various concentrations ranging from 0.025 to 0.1%. The heat transfer features of a tubular heat pipe with a mixture of the ZrO2-CeO2 nanofluid were evaluated. A 5.33% decrease in thermal resistance value and a 41.16% increase in heat transfer ability with increased power input were observed. The potent regression models were proposed to estimate heat transfer features of the heat pipe. The ANOVA statistical method has been employed to determine the P value and the F value of the models towards enhancing the reliability and accuracy of the developed models. The outcome revealed that the proposed models are reliable and have the best fit with the experimental data for 30–60 W power. The correlations’ results were validated against the experimental data and showed high accuracy. Moreover, the accuracy of the developed models was ensured through R -squared and adjusted R -squared values.

Heat transfer studies in a plate heat exchanger using Fe2O3-water-engine oil nanofluid

“…Many similar studies with addition of nanoparticle in a base fluid were shown to enhance the overall heat transfer (e.g. addition of Copper [17], TiO2 and ZnO [18], MgO -TiO2, ZrO2 -CeO2 [19,20], graphene [21,22] in a base fluid Ethylene Glycol-Water mixture).…”

Fully developed opposing mixed convection of a Jeffery tri‐hybrid nanofluid between two parallel inclined plates subjected to wall‐slip condition

“…Utilizing such hybrid nanofluids, various preliminary studies have produced amazing results. For example, Vidhya et al [18] found that hybrid nanofluids have excellent thermal performance potential and are particularly suitable for heat transfer applications. Rajesh et al [19] analyzed the energy augmentation by using hybrid nanofluid in an infinite vertical plate with ramped wall temperature.…”
