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.
Description: Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization.
