Natural convection within a wedge-shaped enclosure has been studied numerically by finite difference method. Radial surfaces of the wedge are isothermally hot and cold while circumferential surfaces are insulated. Results show isotherms, streamlines and velocity profiles as well as Nusselt number distributions for a Rayleigh number range of $10^3$ to $10^5$. In addition, it is found that there is a wedge angle as shown the minimum mean Nusselt number for using an insulated enclosure.
