Simulation of Convective Heat Transfer of a Nanofluid in a Circular Cross-section

Authors

Abstract:

The CFD simulation of heat transfer characteristics of a nanofluid ina circular tube under convective heat transferwas considered using the fluentsoftware (version 6.3.26) in the laminar flow. Al2O3nano- particles in water with concentrations of 0.5, 1.0, 1.5, 2 and 2.5% were studied in the simulation. All thermo-physical properties of nanofluids were temperature independent. It was concluded that heat transfer coefficient increased with the Peclet number. Furthermore, it increased by increasing the concentration of nano-particles in nanofluid. The simulated data were in good agreement with the literature (with the discrepancy of less than 10%).

Convective Heat Transfer of Oil Based Nanofluid Flow Inside a Circular Tube

Abstract   An empirical investigation was carried out to study convective heat transfer of nanofluid flow inside an inclined copper tube under uniform heat flux condition. Required data are acquired for laminar and hydrodynamically fully developed flow inside round tube. The stable CuO-base oil nanofluid with different nanoparticle weight fractions of 0.5%, 1% and 2% was produced by means of ul...

Experimental study of convective heat transfer coefficient of MgO nanofluid in a cylindrical microchannel heat sink

Convective heat transfer of MgO-water nanofluid in a microchannel heat sink is experimentally investigated in various concentrations of 0.01, 0.05, 0.1, and 0.6 wt%. The microchannel consisted of 48 parallel rectangular cross section channels with the height of 800 µm, width of 524 µm and length of 52 mm. A well stability duration (ca. 1 month) was resulted by a 180 min ultra-sonication of the ...

Factor Effect Estimation in the Convective Heat Transfer Coefficient Enhancement of Al2O3/EG Nanofluid in a Double-pipe Heat Exchanger

The forced convective heat transfer (CHT) coefficient of a particular nanofluid, Al2O3 nanoparticles-ethylene glycol (EG) mixture, was investigated experimentally in a double-pipe heat exchanger. The nanofluid Nusselt number for different nanoparticles’ concentrations as well as various operating temperatures was measured to be increased up to 23.7% using 1.0% wt of nanoparticles. The significa...
