Investigation of Critical Submergence Depth in Horizontal Intake of Power Plant for Hydro-Electric Dams
(0) Formation of vortex at the intake of a power plant may cause some problems for the proper operation of the power plant. This phenomenon could make air and floating materials to enter the power plants conduit, causing damages to its equipments. Providing an enough submergence depth for the intake prevent the vortex formation. But due to some other considerations such as the risk of entering sediments to the power plant, designers are forced to choose higher level for the intake installation. Therefore, determination of critical submergence depth plays an important role on designing a power plant. In recent decades, many research with the aim of determining a Critical (minimum) Submergence Depth (CSD) led to some empirical relationships for the prediction of CSD. A comparison between the results of these formulas show a wide range of discrepancies in predicted CSD, confirming the need for further studies for developing a more comprehensive equation. In this study the CSD data for number of large dams, derived from a series of large-scale hydraulic model studies were collected and based on these data a new empirical relationship for predicting CSD was introduced. As the data were collected from a wide range of experimental studies, it is believed that the new formula has a good integrity and accuracy.
