Abstract

Natural convection in an inclined enclosure with a centrally located, complete partition has been investigated by a finite-difference procedure. The thermal conditions along the partition are not known beforehand; rather, they are an outcome of the coupling of the natural convection systems on either side of the enclosure partition. To resolve this coupling, a consecutive calculation procedure is used in which the natural convection on either side of the enclosure is successively solved (until convergence) with information exchange in each cycle of solution. Results have been obtained for enclosures with overall aspect ratios of 1 and 2 for Rayleigh numbers up to 107 and for inclination angles of 30, 45, 60, and 90 degrees. Results indicate that the strength of the convective motion and the average Nusselt number are both considerably reduced owing to the presence of the partition. The partition temperature increases monotonically along its length. For a vertical enclosure, the non-uniformity in the parti...
