Al2O3 nanoparticles were synthesized in deionizedwater using a nanosecond Nd-YAG pulsed laser operating at 1064 nm. The structural, optical and morphological characterizations of the produced nanofluids were pe
Stable mono nanofluids based on Therminol with Al2O3 and TiO2 nanoparticles, and hybrid Al2O3–TiO2 nanopowder as additives are prepared by the two﹕tep method. Oleic acid has been made as a surfactant. The impact of nanoparticle content and fluid temperature on thermal conductivity was ...
Thermal ConductivityElectrical ConductivityAluminum AlloysTo assess the effect of the dispersion of AlOnanoparticles into A356 Al alloy on both the electrical and thermal conductivities, A356/AlOmetal matrix nanocomposites (MMNCs) were fabricated using a combination of rheocasting and squeeze casting ...
However, the high conductivity of metallic and carbon-based fillers prevents their applications in electrical insulation field. Among thermally conductive ceramic particles, Al2O3 nanoparticles [8] are preferred due to their high resistivity, high λ (32 W/mK), and low cost [9,10]. However, ...
An optimal combination was selected with the highest thermal conductivity. Then, Al2O3, Fe2O3, Fe, and Cu nanoparticles with different mass fractions were doped into the organic PCMs, in order to prepare a variety of composite phase change heat storage materials. The results show that four ...
The dimensionless governing parameters of the present work are the nanoparticle in volume concentration, the Darcy number, number of undulations, modified heat conductivity ratio, dimensionless heated part length, and location. Comparisons with other published theoretical and experimental results show good ...
The thermal conductivity of iPP/HDPE/h-BN/Al2O3 composites reach 1.802 W·m−1·K−1. The impact strength and tensile strength reach 13.23 KJ/m2 and 40 MPa, respectively. In addition, the composites maintain ideal dielectric properties. This work offers a feasible strategy to fabricate ...

Lattice Boltzmann approach is involved to depict the impacts of magnetic, buoyancy forces and permeability on nanoparticles migration. To predict properties of Al2O3- water nanofluid, Brownian motion impact has been involved. Outcomes revels that considering higher magnetic forces results in greater ...
(2009), who studied thermal conductivity of Al2O3/water and Al2O3/EG nanofluids for particle sizes ranging from 8 to 282 nm, also found that the enhancement of thermal conductivity decreases as the particle size decreases below about 50 nm. They attributed this to a decrease in the ...
