Direct effect of nanoparticles on the thermal conductivity of CuO-water nanofluid in a phase transition phenomenon using molecular dynamics simulation

Comparative molecular dynamics simulations of thermal conductivities of aqueous and hydrocarbon nanofluids

“…They calculated similar thermal conductivity values for water from 303–323 K, as in our case (i.e., 0.59–0.66 W·m −1 ·K −1 , respectively). Then they added CuO nanoparticles with various volumetric concentrations in the base fluid (i.e., water) and obtained data with a similar temperature interval as obtained in the current research (i.e., above 0.71–0.92 W·m −1 ·K −1 ) [ 44 ]. The MDS results showed that adding CuO nanoparticles enhanced the thermal conductivity of water by 25% (i.e., from 0.6 to 0.75 W·m −1 ·K −1 ).…”

“…Ghasemi et al [ 44 ] used molecular dynamic simulations with EAM and the Dreiding force field to investigate different properties of thermal transport of water/CuO nanofluids. They calculated similar thermal conductivity values for water from 303–323 K, as in our case (i.e., 0.59–0.66 W·m −1 ·K −1 , respectively).…”

“…In Figure 2 Ghasemi et al [44] used molecular dynamic simulations with EAM and the Dreiding force field to investigate different properties of thermal transport of water/CuO nanofluids. They [43] and their molecular dynamics.…”

“…The methodology adopted for the simulation of CuO/water systems by Ghasemi et al [ 44 ] is different from the methodology used in this study. A comparison is provided in Table 1 .…”

“…Moreover, this research gives insights regarding the accuracy of thermal conductivities of aqueous and nonaqueous fluids predicted by molecular dynamic simulation. Finally, these MD simulation results were compared with experimental data [ 43 ] and previously reported simulation results [ 44 ]. Moreover, in earlier research, authors investigated the rheological and diffusion properties of a CuO nanofluid in water-based systems [ 45 ].…”
