Experimental investigation of forced convection heat transfer and friction factor in a tube with Fe3O4 magnetic nanofluid

Experimental Investigation into the Forced Convective Heat Transfer of Aqueous Fe3O4 Nanofluids under Transition Region

“…The above experimental results suggest that it is disadvantaged to raise the forced convective heat transfer efficiency of nanofluid by the increase concentration of the nanoparticles in the present research system. These results are contradictive with the initial expectation and some reports that the FCHT properties of the fluid may be improved by adding some nanoparticles [14,15]. However, we also found that the result is similar with the research results about CuO and TiO 2 nanofluid and Al 2 O 3 nanofluid under natural convective heat transfer conditions [18,19].…”

“…However, according to our investigation, the study is still insufficient about the heat transfer of this nanofluid [11][12][13], and no report is found concerning the forced convective heat transfer (FCHT) of water-based magnetic Fe 3 O 4 nanofluids under full developed transition region. Syam Sundar et al [14] have estimated the FCHT properties of aqueous magnetic Fe 3 O 4 nanofluids under turbulent flow (Reynolds number > 10000) and found that the heat transfer coefficient of the fluids was enhanced by adding the nanoparticles. Li and Xuan [15] have investigated the influence of an external magnetic field to the convective heat transfer of aqueous magnetic fluid flow over a fine wire under the laminar flow region.…”

Investigating the forced convection of magnetic nanofluids

“…There are lots of works study of nanoparticles transport in the magnetic field in the channels [1][2][3]. Sundar et al [1] studied turbulent forced convection heat transfer and friction factor of Fe 3 O 4 magnetic nanofluid in a tube in the absence of magnetic field and developed correlations for the estimation of Nusselt number and friction factor.…”

“…Sundar et al [1] studied turbulent forced convection heat transfer and friction factor of Fe 3 O 4 magnetic nanofluid in a tube in the absence of magnetic field and developed correlations for the estimation of Nusselt number and friction factor. Their results show that the heat transfer coefficient is enhanced by 30.96 % and friction factor by 10.01 % at 0.6 % volume fraction compared to the base fluid.…”

MHD peristaltic transport of spherical and cylindrical magneto-nanoparticles suspended in water

“…2 Applications of such fluids can be seen in heat exchangers, domestic heating and cooling systems, solar collector, photovoltaic thermal systems, thermal energy storage, solar cells, automobile industry, biomedical engineering, radiation therapy, modern drug delivery system etc. Subject to such wide utility several investigations through different aspects of nanofluids are made in the recent past (see few [2][3][4][5][6][7][8][9][10] amongst these and several references therein). Effective thermal conductivity of the nanofluids is of central importance in the analysis of such fluids.…”
