A numerical analysis is performed for the coupling of natural convection heat transfer with surface radiation, in a vertical divided vented channel, which is heated asymmetrically (one wall is isotherm and the other is insulated). The problem has been analyzed using the finite volume method to solve differential equations governing the system. The SIMPLER algorithm was adopted for the treatment of velocity–pressure coupling, and the view factors were determined using a boundary element approximation and a Monte Carlo method. The working fluid (air) is perfectly transparent to the radiation exchange. Results have been obtained for various geometrical parameters, in particular for the size and location of the vent opening, and for different Rayleigh numbers.
