Natural Convection Heat Transfer of Cu-water Nanofluid within a Square Enclosure: A Numerical Investigation
-Garnett model is used to predict the ratio of thermal conductivity. Results are posed
for different values of Rayleigh number and volume fraction, in terms of streamlines, isotherms and local Nusselt number. The effects of nanoparticle volume fraction...
Experimental study of TiO2/Turbine oil nanofluid convective heat transfer
apparatus was made to measure convective heat transfer
coefficient and Nusselt number. Constant heat flux boundary condition and laminar flow regime
were selected. Experimental results clearly indicated that the addition of small amount of...
The Investigation of Nusselt Number using Carbon Nanotube-Ethylene Diamine Suspension in a Two Phase Closed Thermosyphon
In the current study, the Nusselt number performance of a Two-Phase Closed Thermosyphon (TPCT) has been investigated using functionalized carbon nanotube (CNT) with ethylene diamine (EDA) suspension. After synthesis of CNT-EDA/Water nanofluid...
Experimental investigation of metal oxide nanofluid convection heat transfer
In this investigation convective heat transfer of two series of oxide nanofluids including and were studied experimentally. The flow was laminar and constant wall temperature was used as thermal boundary condition. The ...
Forced Convection Heat Transfer of Nanofluids in a Porous Channel
Nusselt number is decreased when the Lewis number is increased.
It is observed that as the Schmidt number is increased, the wall temperature gradient is
decreased and as a consequence the local Nusselt number is decreased. The effects...
Experimental Measurement of Heat Trans of Cuo/Turbine Oil Nanofluid in Circular Constant Heat Flux Boundary Condition
In order to raise the heat transfer coefficient of industrial turbine oil, CuO/turbine oil naonofluid suspension is prepared at volume concentrations of less than 1 vol%. An experimental apparatus was designed and constructed ...
Natural convection of silica nanofluids in square and triangular enclosures: Theoretical and experimental study
In this paper, the values of average Nusselt number and heat transfer coefficient ratio for natural convection of silica/water nanofluids in square and triangular cavities are estimated using theoretical correlations. The correlations that are used...
Laminar Film Condensation on a Nanosphere
on different
condensation parameters including the liquid film thickness, velocity and temperature profiles,
Nusselt number and liquid mass flow rate is discussed. It is found that the increase in the velocity
slip and temperature jump...
Heat transfer characteristics of slip flow over solid spheres
at the front stagnation point where the local Nusselt is itself maximum, owing to the maximum temperature gradient at this point. The results show that due to the opposing effects of the velocity slip and temperature jump, the average Nusselt number variation...
