Using CFD in Hydraulic Structures

Abstract

The theoretical background of the fluid mechanics and hydraulics had been almost completed in the eighteenth nineteenth centuries. Since that day, the physical hydraulic models have helped development of hydraulic structures empirically. Although the advanced analytical and numerical methods have been developed together with fluid mechanics theory, the use of these methods has not been possible in practice until recent years due to computation difficulties. However, with the developing in computer technology and numerical solutions methods, Computational Fluid Dynamics (CFD) techniques have been used widely in the hydraulics such as other relevant scopes, especially since the beginning of the 21th century. In this study, the using of CFD in the hydraulic structures was explained with some examples and the advantage and disadvantage of this method were discussed.
