WebFree-Surface Modeling Flow over a broad-crested weir is a typical air-water two-phase ﬂow. To capture the free surface at the interface between the water and the air, the InterFoam solver in OpenFOAM is used in the present study. This solver is based on the volume-of-ﬂuid (VOF) method developed by Hirt and Nichols [28]. WebIn this contribution, different 3D numerical approaches are applied in order to simulate the behaviour of turbulent flow through a rectangular channel with broad-crested weirs. In addition, water flow velocities, using Acoustic Doppler Velocimetry (ADV) instrumentation, were recorded. Two turbulence quantities are estimated using the laboratory records and …
