Natural convection is simulated in a truncated cone filled with nanofluid. Inclined walls wall have constant temperature where the heat source is located on the bottom wall of the conical container which is thermally insulated. A finite volume approach is used to solve the governing equations using the SIMPLE algorithm for different parameters such as Rayleigh number, inclination angle of inclined wall of the enclosure and location of the heat source. The results indicate that adding nanoparticles into pure water improves its cooling performance especially at low Rayleigh numbers. The inclination angle of inclined wall and the location of the heat source proved to significantly affect the heat source maximum temperature.
