Hydraulic Simulation and Numerical Investigation of the Flow in the Stepped Spillway with the Help of FLOW 3D Software

How to transfer the flood of a dam to the
downstream and reduce its energy is one of the most
important issues in the design of a dam. In recent years,
due to the energy loss along its length, the stepped
spillways have received a lot of attention from
researchers. In this research, the values of energy loss
have been investigated with the help of flow 3D software
with different turbulence equations and their comparison
with laboratory values. The results obtained from this
research show that the model of normalized groups or
RNG has the highest level of accuracy among different
turbulence models.
