The optimized ensembles (continuous curves) have consistently lower series resistances than their unstructured counterparts (dashed curves).…”

In this paper two optimal tree-shaped networks for drinking water and irrigation are constructed by using the constructal approach coupled with the exergy destruction minimization method. It is shown that in the construction of treeshaped network for water distribution, the method of exergy destruction minimization is equivalent to minimizing mechanical irreversibility under a water quality constraint. For both energy consumption and the fluid quality degradation appearing in the network, this study offers new interesting routes for optimizing the system either by the exergy destruction minimization (in that case, both irreversible processes are taken into account in the optimization procedure) or by minimizing one of the two irreversible processes, the other being taken into account as optimization constraint. This paper shows that, for the improvement of performances it is important to focus on the design of an efficient distribution network rather than enhancing only the transport properties.

“…A typical method, i.e., the constructal "volume-point" model [14] , was expanded and used to optimize heat and mass transfer in a solid-gas reactor [15,16] . The "volume-point" conduction problem could be described as how to effectively conduct the heat generated in a fixed volume to a heat sink located on its boundary.…”

Entropy generation minimization for heat and mass transfer process in a solid-gas reactor is carried out based on constructal theory by using triangular elemental area. The aspect ratio of the triangular elemental area is optimized under constraint conditions. A number of optimal triangular elements are assembled to a new large rectangular area, which is optimised again. The procedure is repeated until the control-volume is covered, and the complete analytical results are obtained. The effects of some parameters on minimum entropy generation are analysed by numerical examples. The results show that smaller entropy generation can be obtained when the optimization for a given volume is carried out on the basis of triangular elements than those obtained on the basis of rectangular elements.constructal theory, porous medium, solid-gas reactor, heat and mass transfer, entropy generation minimization
