Abstract


This work reports numerical optimization of natural convection in a square enclosure with local heating of the floor and symmetrical cooling of the sides. This analysis was done to optimize heat transfer from two semiconductors in a square electronic package. It became clear that the major part of entropy generation was due to irreversibility of heat transfer and a small amount of it was related to fluid friction. For heaters with equal power ratio, it is very unpleasant to place heaters near the middle plate of the enclosure, since peak temperatures and entropy generation are maximized.
