Laminar convective heat transfer of Al2O3/water nanofluid through square cross-sectional duct

Investigation of Laminar Convective Heat Transfer for Al2O3-Water Nanofluids Flowing through a Square Cross-Section Duct with a Constant Heat Flux

“…Grid sensitivity testing and comparison among numerical, theoretical [32], and experimental data [27] for the Nusselt number of water.…”

“…For validation of the CFD simulation, experimental data (Heris et al [27]) and theoretical solutions (Equation (13); Sieder-Tate equation [32]) are used for a comparison in which distilled water (base fluid) is employed as the working fluid. To validate the accuracy and reliability of the present CFD analysis, the calculated results are compared with the experimental data [27] and theoretical solutions [32] for the Nusselt number versus the (Peclet number) 1/3 .…”

“…Figure 1 shows the geometrical configuration used in the simulation. A 1.0-m-long duct with a square cross-section area of 1 cm 2 , which is exactly the same as that used in Heris et al ’s experiment [27], is employed. The GAMBIT (Geometry And Mesh Building Intelligent Tool) [31] model is employed to describe the problem.…”

“…Six particle concentrations (0.2, 0.5, 1, 1.5, 2, and 2.5 vol.%) are considered. Furthermore, the effect of the Peclet number on the convective heat transfer coefficient is investigated and the results are compared with those of Heris et al ’s experimental study [27]. …”

Heat transfer performance of two-phase closed thermosyphon with oxidized CNT/water nanofluids

“…Various fluids have been used to transfer energy that is absorbed by the evaporator [7,8]. Recently, because of nanofluids' unique properties with regard to high performance heat transfer, they have begun to attract the interest of many scientists [9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Choi and Eastman [23] were the first to synthesize a new nanofluid that had higher thermal conductivity than the base fluid.…”
