Heat transfer efficiency of Al2O3-MWCNT/thermal oil hybrid nanofluid as a cooling fluid in thermal and energy management applications: An experimental and theoretical investigation

An experimental and theoretical investigation on the effects of adding hybrid nanoparticles on heat transfer efficiency and pumping power of an oil-based nanofluid as a coolant fluid

“…They reported that using this nanofluid would not be advantageous in heat transfer applications. In another investigation, the heat transfer capability of MWCNT-Al 2 O 3 /thermal oil hybrid nanofluid in both the internal laminar and turbulent flow regimes has been studied by Asadi et al [23]. They conducted the experiments in various temperatures ranging from 25 ℃ to 50 ℃ and solid concentrations ranging from 0.125 % to 1.5 %.…”

A Review on Hybrid Nanofluid

“…The method also revealed the structure and function of many biological molecules, including vitamins, drugs, proteins and nucleic acids such as DNA. Stability period of different nanofluid in various article are-References Nanofluid Stability period [2] Al2O3-MWCNTs/thermal oil 7 days [4] Sic-TiO2/diathermic oil 10 days [3] Cu-Zn/vegetable oil 03 days [5] MWCNTs-Fe2o3/water 60 days [6] SiO2-graphene/naphthenic mineral oil 14 days [7] Cu-Tio2/water and EG 07 days [8] Al2O3-Cu/ethylene glycol 03 days [11] MWCNTs-ZnO/water and EG 10 days [10] GNPs-Pt/water 22 days [9] TiO2-SiO2/water 14 days…”

Efficiency and effectiveness enhancement of an intercooler of two‐stage air compressor by low‐cost Al2O3/water nanofluids

“…They observed a slight improvement in overall heat transfer coefficient with an increase in volume concentrations 5 . Asadi et al 6 demonstrated the effects of Al 2 O 3 /MWCNT/thermal oil hybrid nanofluid at different concentrations ranging from 0.125% to 1.5% over temperature range of 25°C to 50°C and reported the maximum increase of 45% at 50°C with 1.5% concentration. Gaffar et al documented a significant improvement in the temperature field inside an inclined tube with uniform heat flux on outer surface when experimented with Al 2 O 3 /water 9 .…”

“…However, there is a need for low‐cost nanoparticles to make a smooth transition from conventional coolants to nanofluids/coolants. Aluminum oxide (Al 2 O 3 ) nanoparticles are one of such low cost and promising candidate for high heat transfer rates 5‐7 …”
