Abstract
An analysis is made of the laminar natural convection in two internally finned horizontal annuli. The governing equations were solved numerically by a control-volume based finite-difference method. Information about the flow patterns and temperature distributions is presented through velocity vectors, streamlines, and isotherms plots. The effects of Rayleigh number of fin height on the Nusselt numbers are presented for two selected fin orientations. The variation of the local Nusselt numbers along the inner cylinder is also presented. In the cases studied, orientations of the internal fins are found to have insignificant effects on the average Nusselt number.
