Abstract
Hydraulic model test was used to analyze the rapidly varied flow on the spillway. But it has some error to scale and expensive cost. KhadakWasla dam in Pune was selected as the study area. The terminal structure of a spillway plays a major role in dissipating specific energy of excess flood to safeguard the river channel and downstream structure. Relationship between critical depth flow and energy dissipation are presented and discussed in stepped spillway. The numerical result is compared with experimental result. Computational fluid dynamic (CFD) software with different numerical solver methods are suitable tools for solving various engineering problems. One such CFD software tool is ANSYS Fluent. In this report, the general guide and practical steps for developing a full 3D CFD spillway model using ANSYS Fluent have been presented. The energy dissipation over this model and pressure distribution on the horizontal and vertical step faces are studied for verification purpose of CFD.
