Abstract

In this recent study we have simulated free surface flow over submerged weirs using the computational fluid dynamics code, Fluent, to forecast flow near the structure where three-dimensional (3D) flows were dominant. The fully 3D, Reynolds-averaged Navier– Stokes equations were solved using the model. To understand the complex flows, the volume of fluid method with genetic reconstruction scheme was adopted and the standard k–ε equations were used for turbulence model. The numerical results obtained using the compressed mesh systems were in accordance with the experimental data.
