Abstract:

In order to prevent cavitational damage on the spillway chutes exposed to high flow velocity, the most effective method is to use aerator devices. In this study, the first design of the Ilisu Dam spillway aerator in 1982 and the performance of the 2010 revision design were investigated using the Computational Fluid Dynamics (CFD) method. First, three-dimensional CFD analysis of the initial 1982 design was conducted and it was determined that the performance of the aerator was inadequate. Secondly, numerical modeling of the 2010 revised design was performed and the aerator performance was studied. Before an incomprehensive study were performed for the revised design of 2010, but the detailed numerical analysis for different flow conditions is presented in this study. The CFD results of both designs are given and evaluated comparatively. The results from the CFD analyzes showed that the aeration performance of the 2010 revised design was much better than the previous one to adequately protect the spillway chute channels from cavitation damage
