Abstract: In this paper the numerical simulation of a free surface flow over a vertical weir
with in turns of a scour pool and a small hump weir is presented. Since in this case few of
calculative examples adds scour pool and small hump weir in the model, it is meaningful to
compute this example using a numerical software which is named Fluent 6.3. The numerical
method used consists of Navier-Stokes turbulence solver and k-Ε model together with a VOF
method and PISO algorithm in pave meshes. Thus, the sketches of flow fields on each typical time
point and velocity distributions on each section on 16s are provided to describe flow field
accurately. A very good quantitative consequence which accords with hydraulics theoretical
analysis has been obtained. © (2013) Trans Tech Publications, Switzerland.
