Determination and measurement of some thermophysical properties of nanofluids and comparison with literature studies

The thermophysical properties of nanofluids must be determined to evaluate their thermal performances like heat transfer, convection transfer coefficient, Nusselt number. purpose this study is obtain the nanofluids. Al2O3, TiO2, and ZnO are used as a nanoparticle, while deionized water base fluid. solutions included nanoparticles in way each with 0.5%, 0.7%, 1.0% volumetric concentration were prepared. SDS was added surfactant prevent instability that occurred due agglomeration sedimentation. For conductivity measurement, device works by transient hot-wire method between 30-60?C temperatures. Also, for viscosity based on vibrating plate 20-50?C Density specific values obtained help well-known equations measured. Thanks study, it emphasized how change according temperature concentration. Moreover, curve fitting obtained. All compared studies literature. It established proportional temperature, concentrations but inversely temperature. Finally, effects augmentation dynamic pumping power considered well increase conductivity; thus, no abnormal enhancement observed.
