| Abstract: | This paper deals with the numerical modeling of the highly complicated interactions between
topography, hydraulic structures and vessels with the two phases water and air. Standard 3D-models
for river hydraulics are not necessarily in the position to describe this phenomenon. For the
approximation a two phase Navier-Stokes solver is indispensable. The goal is accordingly to extend
the parallel 3D two phase flow code NaSt3DGPF for applications in the near vicinity of hydraulic
structures and vessels. The model includes all significant processes relevant to hydraulic structures
at waterways. Providing the transition between water and air the Level Set Method is implemented,
turbulence is modeled by using a LES concept. Regarding an automated meshing of real world
CAD-applications the substantial advantages of using a Finite Difference Method based on a nonuniform
structured grid will be shown. In view of an effective usage of the HPC resources, the
limitations concerning the sizes of the 3D modeling areas, the possibilities of optimizing the grid
spaces and a necessary coupling with 1D far field models are in the focus of interest. The validation
against a laboratory model and recent projects at German waterways with up to 10 million grid
points will be presented. |
