Abstract

The results of a numerical study on simultaneous natural convection and radiation in air filled vertical rectangular enclosures are presented. A non- partitioned enclosure, one with a non-reflecting partition, and an enclosure with a reflective partition were considered. Heat transfer characteristics were studied for a wide range of the governing parameters. The mean enclosure temperature ranged from 250 to 350 K. The enclosure temperature difference ranged from 10 to 40 K. A highly reflective partition may reduce heat flux in the enclosure more than 80% for the temperature conditions considered. The reflective partition modulates the heat flux variation with the change in temperature conditions.
