The present study is devoted to the numerical analysis of entropy generation in the natural convection of water combined with nano-sized particles containing the encapsulated phase change material in a square enclosure with a solid triangular block. The finite element method is used for the current investigation. The effects of the Rayleigh (Ra), Stefan numbers (Ste), thermal conductivity ratio (Rk) and non-dimensional height (LY) of the triangular block, the volume fraction (φ), and the non-dimensional fusion temperature (θf) of the nano-encapsulated phase change materials are reported. The results show that the rate of heat transfer and the total entropy generation enhances with the increment of the thermal conductivity of the solid triangular block and also declines with augmentation of its height. Moreover, the generated entropy intensifies as the volume fraction of the nano-capsules increases. Finally, for high values of the Rayleigh number (Ra = 106), the total entropy generation declines as the non-dimensional fusion temperature (θf) approaches 0.5. In contrast, when the buoyancy force is low (Ra = 104), the total generated entropy elevates as θf → 0.5.
