Abstract
A two-dimensional numerical study of coupled heat transfer by laminar natural convection and surface radiation in a rectangular cavity is performed. The cavity is divided by a rigid vertical partition into two sub-cavities, one filled with water and the other with air. The left vertical wall (water side) is heated uniformly with a temperature TH, while the right vertical wall (air side) is cooled isothermally with a temperature TC. The horizontal walls are supposed to be thermally insulated. The surface radiation is considered only in the air cavity. The authors used the Finite Volume Method to solve the conservation equations, and the Radiosity Method to determine the radiative transfer between the air cavity surfaces. The main subject of the present study is to analyze the influence of some critical control parameters on the convective and radiative heat transfer by analyzing the streamlines, isotherms, and the mean Nusselt numbers.
