1. 16. Jet flow simulations of Baihetan hydropower station’s discharge surface spillways

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Benjamin Blomqvist; Britta Rönntoft; [2015]
   Keywords : CFD; Baihetan; spillway; hydropower;

   Abstract : This project was performed in order to determine if numerical simulations can be used to predict the spreading of a water jet that exits the discharge surface spillways of Baihetan hydropower station. If the spreading ranges can be predicted correctly using numerical simulations, the pressure distribution in the plunge pool downstream the dam can be determined. READ MORE

3. 17. Numerical study on jet flow characteristics of high head and large discharge spillways

   University essay from Uppsala universitet/Elektricitetslära

   Author : Lisa Gerdin; Mira Rosengren Keijser; [2014]
   Keywords : Spillway design; energy dissipation; CFD; Fluent; jet nappe; erosion;

   Abstract : Today scale models are used to design spillway structures for hydropower stations. These are expensive and time-consuming to build and alter. This study investigates the possibilities of using numerical simulations in order to facilitate the spillway design process. READ MORE

4. 18. Safety Analysis of the Baihetan Dam : By Investigating the Pressure Distribution on the Plunge Pool Floor

   University essay from Elektricitetslära

   Author : Viktor Gårdö; Yasmin Lindholm; [2013]
   Keywords : Hydropower; China; Baihetan Dam; safety evaluation; scour; experimental model.;

   Abstract : Baihetan Dam is sited on the lower reaches of the Jinsha River in the southwest of China between the boarders of Sichuan and Yunnan province. The dam is scheduled to be taken into operation in the year of 2020 with an installed generation capacity of 14 GW which will put Baihetan Dam on the map as the third largest hydropower station in the world considering installed power output.

5. 19. Flow conditions downstream of Bergeforsen dam

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Erik Lidén; [2012]
   Keywords : Bergeforsen; Indalsälven; spillway; dam safety; design flow; flow conditions; erosion; SMS; Surfacewater Modeling System; RMA2; Technology and Engineering;

   Abstract : Due to the change in climate the design flow for Bergeforsen dam, located at the Indalsälven river mouth, is being revised from 2300 m3/s to more than 3000 m3/s. The dam needs to be upgraded with a new gated spillway and repaired in order to increase the safety of the dam. READ MORE

6. 20. Safety Evaluation of the Plunge Pool and the Downstream River of the Baihetan Hydropower Station Using Model Experiments

   University essay from Mekanisk värmeteori och strömningslära

   Author : Johan Pettersson; Henrik Pettersson; [2011]
   Keywords : ;

   Abstract : As a part of the hydropower expansion in China, the Baihetan Hydropower Station is now being constructed in the southern parts of the country. This hydropower station will, when completed, become the third largest in the world in terms of installed power output. READ MORE
