Abstract EN
Turbulent forced convection flow of Al2O3/water nanofluid in a single-bare subchannel of a typical pressurized water reactor is numerically analyzed.
The single-phase model is adopted to simulate the nanofluid convection of 1% and 4% by volume concentration.
The renormalization group k-ε model is used to simulate turbulence in ANSYS FLUENT 12.1.
Results show that the heat transfer increases with nanoparticle volume concentrations in the subchannel geometry.
The highest heat transfer rates are detected, for each concentration, corresponding to the highest Reynolds number Re.
The maximum heat transfer enhancement at the center of a subchannel formed by heated rods is ~15% for the particle volume concentration of 4% corresponding to Re = 80,000.
The friction factor shows a reasonable agreement with the classical correlation used for such normal fluid as the Blasius formula.
The result reveals that the Al2O3/water pressure drop along the subchannel increases by about 14% and 98% for volume concentrations of 1% and 4%, respectively, given Re compared to the base fluid.
Coupled thermohydrodynamic and neutronic investigations are further needed to streamline the nanoparticles and to optimize their concentration.
