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

This article experimentally and statistically reports the convective heat transfer performance of a cylindrical mesh-type pipe apparatus filled with ZrO2-CeO2/water-ethylene glycol nanofluids. In this regard, ZrO2-CeO2 nanoparticles were synthesized characterized through Scanning Electron Microscope Powder X-ray diffraction methods followed by preparation hybrid nanofluids various concentrations ranging from 0.025 to 0.1%. The features tubular mixture nanofluid evaluated. A 5.33% decrease in thermal resistance value 41.16% increase ability increased power input observed. potent regression models proposed estimate pipe.
