Effect of Morse potential as model of solid–solid inter-atomic interaction on the thermal conductivity of nanofluids

The behavior of the thermal conductivity near the melting temperature of copper nanoparticle

“…Before leaving this section, it is important to show that the melting temperature of the nanoparticle decreases with decreasing the nanoparticle size, and there is a good agreement between the theoretical values calculated by Eq. (14) and the values calculated by MD simulation via the investigation of the total energy and heat capacity. The good agreement between our predicted and theoretical values indicates that the embedded atom method potential is more appropriate to describe a Cu-Cu interaction.…”

“…5 the melting temperature of the Cu nanoparticle as function of its size calculated theoretically from Eq. (14) and by MD simulation using EAM potentials. The results indicate that the predicted values are qualitatively consistent with theoretical model and the deviation observed is smaller and remain in the range of acceptable values.…”

“…These features lead to potential application in many industrial sectors, particularly nanofluids which are used in cooling fluids for electronic systems, heating, cooling exchanger including transportation and energy production. Therefore, nanofluids containing suspended nanoparticle of copper showed large enhancement of thermal conductivity relative to those of pure fluids such as (Cu-Ar) nanofluid [13,14]. Extensive literature has been conducted in the past decade to investigate and predict various proprieties, heat transfer performance and the effective thermal conductivity of nanofluid consisting of several nanoparticles [15][16][17][18][19][20][21].…”

Heat Transfer Characteristics of Nanofuid Flow around an Elliptical Cylinder

“…At this circumstance, the use of nanofluids with higher thermal conductivity can be considered as a promising solution [17][18][19]. However, in recent years there have been some new efforts to produce a new class of high efficiency heat exchange media, to highlight the effect of nanoparticles during flow past bluff bodies [1][2][3][4][5].…”
