Abstract
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.
Keywords: water distribution network, constructal theory, exergy, optimization
drinking water, irrigation.
1 Introduction
Several areas of engineering involve tree-shaped networks: electronic
components cooling Bejan [1], heat and mass transfer in a solid-gas reactive
porous media Azoumah et al. [2] or most generally flow structures [3, 4].
The optimal implementation of these flow systems depends greatly on their
irreversibilities minimization. For the specific case of water piping systems two
