Natural convection is gaining more consideration as it has become crucial to remove unwanted heat from a product and is likewise monetarily reasonable. The present research focuses on numerical analysis of the heat transfer and flow dynamics from the hot cylindrical body that is in a square enclosure with incompressible fluid as a working medium. The problem for numerical analysis for natural convection induced by a temperature difference between a cold outer square enclosure and a hot inner cylinder for various Rayleigh numbers ranging (103–106) is considered and further investigated for the flow pattern and heat transfer which would effectively change by the introduction of another small cylinder inside the square enclosure. The results show a 10.34% enhancement in heat transfer when two bluff bodies are introduced at the upper half of the enclosure, compared to the study without any confined bodies nearer.
