Abstract: The natural convection in a Cu–water nanofluid filled and partially heated annulus between two elliptical cylinders is numerically analyzed. A cold temperature Tc is imposed on the outer cylinder while heaters are placed on the inner cylinder wall in three different configurations. The flow governing equations are written under the Vorticity–Stream function dimensionless formulation and solved with a developed code using FORTRAN platform. The results are given by the finite-volume method in the ranges of Rayleigh number (103Keywords: Partial heating; Annulus; Elliptic cylinders; Nanofluid (search for similar items in EconPapers)
