Overview of Large-Scale Smoothed Particle Hydrodynamics Modeling of Dam Hydraulics
The design of appurtenant structures for dams, such as spillways, is a complex task because of the turbulent high-velocity aerated nature of the flowing water. In previous years, physical models would have been the only practical tool available to gain insight into the three-dimensional and time-dependent nature of spillway flows. Now, hydropower dam designers have multiple engineering tools to assess the hydraulic behavior in spillway structures. The high complexity level of these flows challenges the capabilities of computational fluid dynamics methods. Within this scope, the smoothed particle hydrodynamics method appears as a quite appropriate solution to solve flows dealing with large deformations, complex geometries, and movable boundaries. It has been used in a wide range of applications, including dam spillways. This paper provides an overview of how this method has been applied to investigate flow features in real spillways within the past decade. Its current state of knowledge with relevance to dam engineering practice is addressed and current limitations are highlighted in sight of future research could resolve them.
