Abstract A numerical modelling technique is developed to examine the effects of a heat source located in a partially partitioned enclosure on the natural convection flow within the enclosure. The heat source is located on the insulated left vertical wall, while the right vertical wall of the enclosure is maintained at a low temperature. The horizontal walls of the enclosure are also thermally insulated. A two-dimensional, laminar, Newtonian and incompressible flow is considered in the analysis. The system of governing equations for a domain within the enclosure is solved through a control volume formulation of finite difference method. The SIMPLE algorithm is used to handle the pressure-velocity coupling. The results of this study are presented in terms of flow patterns, isotherms and heat transfer rates at different Rayleigh numbers. At low Rayleigh numbers, the buoyancy forces are not strong enough to generate adequate circulation and to provide a uniform temperature distribution in the enclosure. At high Rayleigh numbers, the flow circulation extends the whole enclosure and a more uniform temperature distribution is achieved.
