Abstract

Laminar forced convection of Al2O3/water nanofluid in a circular cross-section horizontal tube under constant surface heat flux has been studied numerically by employing single-phase model. The particle volume concentrations considered for analysis are 1%, 1.5% and 2% while the nano-particle size is 100nm. Effect of some parameters i.e. nano-particle concentration, surface heat flux and Reynolds number on the heat transfer characteristics has been analyzed. Selected range of Reynolds number is 200-1000. When compared with the previous published numerical and experimental result, it has been concluded that by applying a suitable correlation for the calculation of nanofluid effective thermo-physical properties, nanofluid heat transfer characteristics can be predicted accurately using the single-phase model.
