== University Thesis (Barton, 2001) ==
This thesis study investigated the ability of 2D hydrodynamic models to adequately predict energy losses through an abrupt constriction. In particular, the investigation focuses on the impact that model spatial resolution has on the ability of the model to predict expansion and contraction losses due to the abrupt constriction.
Principal outcomes of the study were:
* An improved understanding of different numerical solution schemes;
* An improved understanding of the nature of contracting and expanding flow;
* The confirmation that the spatial resolution of 2D models does have an impact on the ability of
these models to predict energy losses due to turbulent effects;
* An understanding of the importance of the eddy viscosity formulation technique on the predictive
ability of 2D models;
* A preliminary assessment of the impact of varying the eddy viscosity formulation technique.
