Nanofluids formed by adding a small volume fraction of solid nanoparticles to the conventional fluid can greatly enhance the thermal transport performance of the conventional fluid. This study reveals the mechanism of thermal conductivity by studying the microscopic effect of nanoparticles in a Cu–Ar nanofluid on the base fluid. Due to the presence...

In this paper, we study the magnetic properties of a tri-layer graphyne-like structure using Blume-Capel Ising model. The studied system is composed by a mixed spins σ = ± 5/2, ± 3/2 and ± 1/2 (in the plane B) and S = ± 2, ± 1 and 0 (in the plane A). The study is performed through Monte Carlo simulations under the Metropolis algorithm. Besides, we ...

Densities of two synthetic biomethane-like mixtures were measured in the homogeneous liquid phase and the supercritical region using a low-temperature single-sinker magnetic-suspension densimeter. Both mixtures consist of methane, nitrogen, hydrogen and oxygen, whereas the second mixture additionally contains carbon dioxide. For the first mixture, ...

In the field of water content measurement, the calibration of coulometric methods (e.g., coulometric Karl Fischer titration or evolved water vapor analysis) is often overlooked. However, as coulometric water content measurement methods are used to calibrate secondary methods, their results must be obtained with the highest degree of confidence. The...

Ammonium dihydrogen phosphate (ADP) crystal utilizes several applications such as Q-switching, electro-optical, and second harmonic generation in nonlinear optics. In the present article, a good-quality single crystal of ADP was grown via Sankaranarayanan–Ramasamy (SR) method for the dimension of 120 mm in length and 12 mm in diameter. The grown AD...

The thermal conductivity of liquid and gas-saturated glass sieves (frits) of porosities between 20 and 48 % is presented as measured at room temperature and ambient pressure. The saturating fluids cover a range in thermal conductivity from 0.018 W⋅m−1⋅K−1 to 0.598 W⋅m−1⋅K−1. The experimental results are fitted to a simple two-dimensional composite ...

Group contribution models can be used to predict the thermodynamic properties. The basic data used to determine the interaction parameters are VLE, HE and infinite dilution activity coefficient data. However in the absence of the required data, SLE measurements of eutectic systems are of great interest for fitting interaction parameters of group co...

The preparation and utilization of hybrid nanofluids in thermal systems have become popular nowadays owing to their improved thermophysical properties. Although a nanofluid suspension increases the performance of the thermal system, hybrid nanofluids improve the heat transfer performance more by removing the disadvantages of each component. The aqu...

This research aimed to investigate the feasibility of a new combination of hybrid nanolubricant that can enhance the vibration and noise characteristics of an automotive spark-ignition engine through a comprehensive study of rheological and heat transfer behavior. The ZnO-based mono (ZnO/5W30) and hybrid (ZnO–TiO2/5W30, 50:50) nanolubricants of 0.1...

Thermal conductivity of concrete greatly influences the heat transfer of buildings and affected by many factors. This paper presents a prediction model for thermal conductivity of concrete by adopting the theory of Wiener bounds and considering concrete to have four components (water, air, aggregate, and cement mortar). The proposed model considers...
