Abstract EN
Turbulent forced convection flow of a water-Al2O3 nanofluid in a circular tube subjected to a constant and uniform temperature at the wall is numerically analyzed.
The two-phase mixture model is employed to simulate the nanofluid convection, taking into account appropriate thermophysical properties.
Particles are assumed spherical with a diameter equal to 38 nm.
It is found that convective heat transfer coefficient for nanofluids is greater than that of the base liquid.
Heat transfer enhancement is increasing with the particle volume concentration and Reynolds number.
Comparisons with correlations present in the literature are accomplished and a very good agreement is found with Pak and Cho (1998).
As for the friction factor, it shows a good agreement with the classical correlation used for normal fluid, such as Blasius formula.
