Enhanced Thermophysical Properties of 40:60 % Ethylene Glycol and Water Mixture Based MgO + Fe3O4 Hybrid Nanofluids: An Experimental and ANN Predictions

Characterization of spark-discharge–synthesized multi-element oxide nanocomposites and thermophysical performance of their water-based nanofluids for solar collectors

Thermophysical Properties And Heat Transfer Performance Of N-Doped Carbon-Metal Oxide Nanocomposite Nanofluids

Nanofluids, made by dispersing solid nanoparticles in a base fluid such as water or ethylene glycol, raise the thermal conductivity of ordinary coolants but come with two familiar penalties: the viscosity rises with loading, and the particles tend to settle or clump over time. Nitrogen-doped carbon combined with a tran...

Effect of Titanium Dioxide (TiO2) Nanoparticle Concentration on the Thermal Conductivity and Stability of Water-Ethylene Glycol Nanofluids

Nanofluids have attracted considerable attention for their potential use as advanced heat transfer media in various cooling applications. This study investigates the effect of titanium dioxide (TiO2) nanoparticle concentration on the thermal conductivity and stability of nanofluids. Five concentrations of TiO2 nanoflui...

Effect of Al₂O₃ nanoparticle dispersion on the thermophysical properties of an ethylene glycol-water coolant for automotive applications

This experimental study evaluates Al₂O₃ nanoparticles dispersed in a 50:50 ethylene glycol–water (EG/W) mixture as an automotive coolant. Nanofluids containing 0.5–3.0 wt% Al₂O₃ were prepared by a two-step method and tested at 30–90 °C. FE-SEM, TEM, and XRD were used for particle characterization; dispersion stability...

Model-Based Prediction and Comparative Analysis of Density and Specific Heat Capacity of CuO and Graphene Oxide Nanofluids in Water–Ethylene Glycol

Density and specific heat capacity are two very important thermo-physical properties used in evaluating the suitability of nanofluids for heat transfer and thermal management applications. In the present study, a model-driven comparative evaluation of copper oxide (CuO) and graphene oxide (GO) nanofluids suspended in a...

Temperature-Driven Formation and Consolidation of Magnetite-Type Nano-Assemblies in a PEI-Assisted Solvothermal System

Magnetite-type iron oxide nano-assemblies are widely investigated because of their strong magnetic response, chemical stability, and tunable surface chemistry. However, the lower-temperature threshold for crystalline spinel formation in polyethylenimine-assisted solvothermal systems remains insufficiently defined. In t...
