In this research work natural convection in two dimensional enclosure is studied numerically for differently heated air filled square enclosure with inner square and circular cavity. The inner circular and square wall kept at high temperature while the outer square wall maintain at low temperature. The natural convection is obtained by using the finite volume method in enclosed square enclosure for different Rayleigh numbers varying over the range of 104 –106. In order to study the flow field and temperature distribution these investigation further extended by changing the location of square and circular inner cavity in vertical position. The result obtained by CFD analysis it shows that the nussalt number and size of eddies of flow field strongly depended on Rayleigh no and position of At low Rayleigh No 104 the bicellular vortices to an uni-cellular vortex occurs when an inner cavity is placed at a maximum distance from the center of the enclosure.in case of higher Rayleigh No. Uni cellu vortex id formed in inner space of cavity. The average Nussalt No of the enclosure show minor deviation for each Rayleigh number but its better in case of circular inner cavity. The Pressure-Velocity Coupling Method used with Non-Iterative Time Advancement (NITA) scheme used to solve the problem. The distribution of temperature and stream function are taken as a function of thermal and geometrical output parameter for given problem. Two stage investigations have been performed to find out the variation in the result between different approaches.
