Abstract

In the present research, the flow on a free dam is modeled in 3D environment of Flow-3D software, then the software results were validated in comparison with results obtained from the physical model. Finally, the effect of various types of ramps on effective factors of Vacuum creation was scrutinized. The results for Vacuum creation index and air concentration existing within the flow revealed that a Spillwaywith ramp at the bed and a wall equipped with duct, and a Spillway with ramp at bed and wall, leads to %22, %22 and %19 increase in Vacuum creation index, respectively...
