Laminar mixed convection of a nanofluid in horizontal concentric annulus, Part ІI: Heat transfer

Fully developed laminar mixed convection of a nanofluid consisting of water and Al2O3 in a horizontal annulus has been studied numerically. Threedimensional elliptic governing equations have been used. The nanoparticles volume fraction does not have a direct effect on the dimensionless temperature and convective friction coefficient. Contour of the dimensionless temperature are symmetry respect to horizontal plane at low value of Richardson number while symmetry deforms at large value.
