The motion of water in a complex hydrodynamic configuration is characterized by a wide
spectrum of space and time scales, due to the coexistence of physical phenomena of
different nature. Consequently, the numerical simulation of a hydrodynamic system of this
type is characterized by a large computational cost. In this paper, after providing a quite
general setting for model coupling, we introduce a first possible technique to reduce such a
computational effort, by suitably coupling different hydrodynamic models, namely a …

In view of the numerical simulation of a complex hydrodynamic system, we provide in this
paper a possible strategy, alternative to that one proposed in the first part of this work [Miglio
et al., Proceedings of the Fourth World Congress of Nonlinear Analysis WCNA-2004,
Orlando, FL, USA, 2004, accepted]. The main aim of both the approaches is to contain the
computational cost of the numerical simulation without compromising the accuracy of the
proposed mathematical model. In more detail, we introduce here a dimensionally …
