Modeling Free-Surface Flow Over a Weir

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.
