There are some simplifications of the GTB cooling model in
this paper. The shapes of the GTBs are not rectangular ones,
and the heat transfer boundary conditions as well as the heat
transfer regimes are more complex for real GTBs. Moreover,
the design of the GTB is not merely the content of a single
discipline, but that of multi-disciplines. Therefore, one can
establish a more real GTB model to further carry out multidisciplinary
constructal design of the GTB.
