CFD Analysis of Ilısu Dam Sluice Outlet

Abstract

Ilisu Dam is one important energy projects in Turkey. After it is completed, it is expected that it will contribute to the country economy approximately $300 million annually. One of the most remarkable engineering designs of the dam is the conversion of diversion tunnels of 12 m in diameter and about 1 km in length into sluice outlet structure. In this study, the CFD simulation of Ilısu Dam sluice outlet were performed with 1/40 scale. The obtained CFD results were compared with physical model observations conducted by the State Water Works (SWW). A good agreement was achieved between both results, and some useful results of CFD were presented for design of the outlet.
