Development, Thermal Properties, and Reliability Testing of Eutectic Polyethylene Glycol as Phase Change Materials for Thermal Energy Storage Applications

Pooja Singh et al.

Summary: This study outlines the development of eutectic phase change material (PCM) with different mass fraction ratios and determines its thermal properties. The eutectic mixture was prepared using polyethylene glycol (PEG) with atomic weights of 10,000 and 6,000. The phase transition temperature and fusion latent heat were evaluated using differential scanning calorimetry (DSC), while the chemical composition was analyzed using Fourier transform infrared spectroscopy (FT-IR). The results show that the sample with a mass fraction ratio of PEG 6,000 to PEG 10,000 of 60:40 has the highest latent heat of fusion at 194.52 J · g(-1). The durability of the eutectic PCM was evaluated through 1,500 cycles of thermal melt/freeze tests and thermal gravimetric analysis (TGA). The findings indicate that the variation in latent heat of fusion is less than 15% and the chemical properties remain unchanged after 1,500 cycles. The prepared eutectic PCMs show potential for use in medium-temperature solar-based energy storage applications.

Thermodynamic Properties and Critical Behavior of Spin-Polarized Atomic Hydrogen (H?) Using the Quantum Second-Virial Coefficient

B. R. Joudeh

Summary: The quantum-mechanical formulations for the second-virial and acoustic virial coefficients are derived for spin-polarized atomic hydrogen (H down arrow), and the dependence of these coefficients on temperature T and nuclear polarization zeta is analyzed. This study provides a comprehensive analysis of the thermophysical properties for this system and explores the T and zeta dependence of these properties.

Reference Correlation for the Viscosity of Ethanol from the Triple Point to 620 K and Pressures Up to 102 MPa

Sofia Sotiriadou et al.

Summary: We have developed a correlation for the viscosity of ethanol based on experimental data. It can be used in a wide temperature and pressure range, and has estimated uncertainties of 4.2% for the liquid and supercritical phase and 2% for the gas phase. Additionally, we propose another correlation for viscosity calculations at 0.1 MPa with an uncertainty of 2.3%.

Thermophysical Properties of Indium(I) Iodide Crystals

Arne Croll et al.

Summary: Thermophysical properties of InI, including thermal expansion, specific heat, and thermal diffusivity, were measured. The anisotropic thermal expansion coefficients were determined by X-ray diffraction, specific heat was measured by DSC, and thermal diffusivity was measured by the Xenon Flash method. This study also confirms that reported phase changes in older literature are actually oxidation effects.

Assessment of Thermophysical Properties of Hybrid Nanoparticles [Graphene Nanoplatelets (GNPs) and Cellulose Nanocrystal (CNC)] in a Base Fluid for Heat Transfer Applications

M. Sandhya et al.

Summary: This article comprehensively investigates the preparation and thermophysical properties of single and hybrid nanofluids. It characterizes nanoparticles using various analytical techniques and measures the thermal conductivity, viscosity, density, and specific heat capacity of the nanofluids. The study finds that both single GNP nanofluids and hybrid nanofluids exhibit favorable thermal properties and can be considered as alternatives to conventional/water-based fluids in operational systems.

Thermophysical Properties of Bentonite-Sand/Fly Ash-Based Backfill Materials for Underground Power Cable

Pawan Kishor Sah et al.

Summary: The surrounding backfill materials play a crucial role in dissipating heat from underground power cable systems during operation. It is important to have backfill materials with adequate thermal properties and water retention capacity to minimize moisture migration while transferring heat. This study systematically evaluates the thermal properties of two backfill materials, bentonite-fly ash and bentonite-sand, under different dry densities and water contents.

Density and Viscosity Measurements of n-Dodecane and Carbon Dioxide plus n-Dodecane at Temperatures from (298 to 548) K

Ximei Liang et al.

Summary: A vibrating-wire apparatus was used to simultaneously measure liquid density and viscosity under high-temperature conditions. Measurements were conducted for n-dodecane at temperatures ranging from (298.15 to 548.15) K and pressures up to 10 MPa, and for carbon dioxide + n-dodecane at temperatures ranging from (303.15 to 548.15) K and equilibrium pressures up to about 6 MPa. The estimated uncertainties for density and viscosity were 0.24% and 2.2% respectively, with a confidence level of 0.95 (k = 2). Correlations were made with the modified Tait equation and Tait-Andrade equation, and showed good agreement with literature data and experimental results.

Rui Chen et al.

Summary: In this paper, the diffusion behavior of water in nano-Al2O3 modified natural ester was studied using molecular dynamics method. The results show that nano-modification can effectively reduce the effect of temperature on water molecular diffusion and inhibit water diffusion, which is conducive to improving the breakdown voltage of natural ester and delaying the aging of insulation system of power equipment.

Turbulent heat transfer and flow analysis of hybrid Al2O3-CuO/water nanofluid: An experiment and CFD simulation study

Shaojie Zhang et al.

Summary: The study investigates the heat transfer performance of a hybrid nanofluid in a circular tube, finding a relative enhancement in heat transfer efficiency and pressure drop at different flow rates. Different thermophysical property models lead to variations in Nusselt and Reynolds numbers, affecting the overall performance of the nanofluid. The numerical simulations demonstrate deviations among different models, with some showing more accurate predictions for experimental heat transfer coefficient than others.

Reference Correlation for the Viscosity of Xenon from the Triple Point to 750 K and up to 86 MPa

Danai Velliadou et al.

Summary: A new wide-ranging correlation for xenon viscosity is presented, based on recent theoretical calculations and critically evaluated experimental data. The correlation is valid up to 750 K and 86 MPa, with estimated uncertainty ranging from 0.2% to 3.6%. It includes a term accounting for critical enhancement and behaves reasonably when extrapolated to 200 MPa, but caution should be taken when using it outside the validated range.

Effects of surfactant on thermal conductivity of aqueous silica nanofluids

Khalid H. Almitani et al.

Summary: The effects of different surfactants on the thermal conductivity of Silica/DI water nanofluids were investigated in this study. The study revealed that the thermal conductivity of the nanofluids increased with temperature or volumetric concentration for all surfactants, with anionic and nonionic surfactants resulting in the highest and lowest thermal conductivities, respectively (anionic > cationic > nonionic). The ratio of variations in Relative Thermal Conductivity (RTC) to temperature or nanoparticle concentration increased with an increase in nanoparticle concentration.
