چکیده مقاله
The main objectives of the present research were to simulate flow over an ogee spillway by a commercial numerical model and investigate the ability of the model to predict several characteristics of flow At ten different flow head, discharge and pressure were obtained by physical model, that constructed with plexiglas and placed in a test flume k ε Standard is used for turbulent modeling in finite volume method and volume of fluid is used to predict free surface of flow Numerical results have a good agreement with physical model results and also with data interpolated from U S Army Corps of Engineering and U S Bureau of Reclamation design monographs This compatibility has shown in nondimensional curves The numerical modeling has shown efficiency in studies due to saving time and money and ability of monitoring all necessary data in several conditions
