Abstract
In this paper, laminar forced convection of a nanofluid consisting of water and Al2O3 in a horizontal annulus has been studied numerically. A two-phase mixture model has been used to investigate thermal behaviors of the nanofluid over constant temperature thermal boundary condition and with different volume concentration of nanoparticles. Comparisons with previously published both experimental and analytical works on flow behavior in horizontal annulus show good agreements between the results as volume fraction is zero. In general, convective heat transfer coefficient increases with nanoparticle concentration.
