Flow over dunes

This case is a simulation of water flow over a dune. Two geometries were used: One from the University of Iowa, USA, and the other from the University of Auckland, New Zealand. The figures below shows the results from a run with the k-epsilon model on the dunes from Auckland. Data from the case was given by Coleman (2006).

Horizontal water velocity.

Vertical water velocity.


Turbulent eddy-viscosity.

Turbulent kinetic energy.

The research is being carried out in cooparation with Dr. Thorsten Stösser at Georgia Institute of Technology and Prof. Wolfgang Rodi at the University of Karlsruhe.
