Multimode heat transfer in an enclosure with multiple partitions

Abstract

A two-dimensional numerical study of the interaction between laminar natural convection and surface radiation in a differentially heated partitioned square enclosure is considered. In analysing this geometry, the partitions are assumed to be very thin. A systematic parametric study is carried out for a range of parameters such as wall temperatures, Rayleigh numbers, partition materials, and surface emissivity values usually encountered in practical applications. Results indicate that surface radiation effects play a significant role in the determination of the heat transfer characteristics within the enclosure.
