Thermal radiation in a room: numerical evaluation

This paper describes the use of the discrete transfer method for the calculation of radiative heat transfer in heated situations within buildings. The principal features and the flexibility of the method are illustrated by considering a number of representative thermal conditions found in room configurations. Results obtained by the discrete transfer method are compared with the results from the standard matrix method. The study also demonstrates how the discrete transfer method is capable of evaluating the distribution of heat fluxes on wall surfaces in complex geometrical situations. Its use has a clear advantage in situations where the standard methods require considerable user input.
