✦ Synopsis

Abstraet--A numerical study by the multigrid technique has been performed to investigate the laminar natural conw:ction air cooling of a vertical plate with five wall-attached protruding, discretely heated integrated cir:uit (IC) packages. This study is of great practical importance because it shows the influence of the blockages (IC package) dimension, and of their power distribution on the buoyancy-induced flow and thermal field in such a configuration. A two-dimensional, steady state model is used to describe the conjugate natural convection/conduction heat transfer. The fluid physical properties are assumed uniform except for the buoyancy terms which are computed using the Boussinesq approximation of Navie~Stokes equations. The development of the buoyancy-induced flow has been studied through the evolution of the streamwise velocity, temperature and heat flux fields.
