Résumé

The heat transfer by natural convection and surface radiation in a two-dimensional vented enclosure in contact with a cold external ambient and a hot internal ambient was studied numerically. The first part of the study focuses on the conjugate problem of natural convection and wall conduction for various thermal resistances of the cold wall, considered as the main floating parameter through the present study. The effects of surface radiation are discussed in the second part of the paper. The interplay between convection and radiation is discussed and it is shown that radiation contribution in heat transfer dominates for all of the cases investigated.
