NATURAL-CONVECTION FROM A WAVY CONE

The problem of natural convection flow and heat transfer induced by a vertically oriented cone with constant surface temperature is treated in this paper. The cone is assumed to have transverse wavy configurati ons. The resulting boundary layer flow is described by two coupled par abolic partial differential equations. These equations are solved nume rically using the Keller-box method for a sinusoidal wavy cone. The ef fect of sinusoidal waves on the local Nusselt number is determined and presented on graphs. The local Nusselt number is found to be lower th an that of the corresponding flat cone.
