要約

A three-dimensional numerical study was performed on interactions of natural convection and radiation in a cubical enclosure filled with a non-gray gas. The enclosure was heated differentially by a set of opposing side walls. The remaining surfaces were thermally insulated. Gas radiation was analyzed by the P1-differential approximation method and the Weighted Sum of Gray Gas model. Computations were carried out for Rayleigh numbers of 1.67×l05 and 4.5×l06. The Prandtl number and the overheat ratio were held fixed at 0.68 and 1.0, respectively. The solutions were compared with previously obtained two-dimensional results. Three-dimensional characteristics of the flow and temperature fields were investigated.
