Abstract:

This Coastal and Hydraulics Engineering Technical Note CHETN investigates the ability of a modeling scheme to compute not only the flow variables pressure and velocity, but also the location of the free surface. The free-surface scheme is implemented in the three dimensional 3-D Navier-Stokes module of the Adaptive Hydraulics ADH code and provides a means to model free-surface flow over a hydraulic structure. A review of existing methods of free-surface tracking is provided. A particular form of a moving-mesh algorithm is tested by comparing simulation results of flow over a weir with published data.
