  1. 1. Hydrodynamic Characteristics of the Baihetan Plunge Pool : The Secondary Dam’s Top Elevation Impact on Flow Patterns

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Henrik Smeds; Axel Monthan; [2018]
    Nyckelord :Baihetan; Plunge Pool; Impinged jets; Flow pattern;

    Sammanfattning : The hydrodynamic characteristics of the Baihetan Plunge pool and the impact of changing the secondarydam’s top elevation was investigated. Quantities such as the velocity distribution, turbulencedissipation rate, water surface profile and the probability of a submerged jump forming in the plungepool was studied. LÄS MER

  3. 2. Computational fluid dynamics study of the spillway and plunge pool at Baihetan hydropower station : Numerical validation of the pressure distribution on the floor of an inverted-arch plunge pool

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Anders Ramqvist; Martin Länsmans; [2017]
    Nyckelord :;

    Sammanfattning : Large-scale hydropower plants with high discharge flow and spillway heads cause high pressure on the downward plunge pool, resulting in erosion of the riverbed, which could ultimately lead to a dam failure. There is an interest of examining the pressure distribution on the plunge pool floor in order to locate where the pressure peaks most frequently occur. LÄS MER

  4. 3. Design Optimization of Spillways at Baihetan Hydroelectric Dam

    Master-uppsats, KTH/Energiteknik

    Författare :Jack Lönn; Oskar Dahl; [2016]
    Nyckelord :;

    Sammanfattning : China’s economic prosperity has led to a massive development in the hydropower sector. The Baihetan hydropower project is an ongoing construction and will become the third largest hydroelectric power plant in the world in regards to generating capacity and is projected to be finished in the year 2020.

  5. 4. Jet flow simulations of Baihetan hydropower station’s discharge surface spillways

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Benjamin Blomqvist; Britta Rönntoft; [2015]
    Nyckelord :CFD; Baihetan; spillway; hydropower;

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

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

    Sammanfattning : 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.
