  1. 1. Effects of surface roughness on spillway flow behaviors

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Oday Asalya; Joar Fjällborg; [2023]
    Keywords : CFD; ansys fluent; roughness height; ytråhet;

    Abstract : This thesis examines the impact of spillway surface roughness on discharge capacity determination in hydraulic models. The study combines physical hydraulic modeling in a laboratory with Computational Fluid Dynamics (CFD) modeling using Fluent. READ MORE

  3. 2. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Alexander Lindblad; [2022]
    Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

    Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

  4. 3. Spillway flow behaviours with and without aeration

    University essay from KTH/Teknisk mekanik

    Author : Noel Köhler; [2022]
    Keywords : Hydropower; Aeration; Computional Fluid Dynamics CFD ; Spillway; Subpressure; Black Water; Spreading;

    Abstract : Cavitation has been known for a long time to cause damages in spillways athydropower plants, aerators are therefore often implemented to prevent this.The majority of the hydropower plants in Sweden are installed in the northernpart of the country. READ MORE

  5. 4. Simulation of spillways with the CFD software code_saturne

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Guillaume Coulaud; [2022]
    Keywords : ;

    Abstract : EDF operates 433 hydroelectric facilities throughout France, which must comply with strict safety rules. Spillways are one of the main components of hydraulic structures which ensure their safety in the event of a flood, by releasing flood water. READ MORE

  6. 5. Production Process for Tunnel Modeling : An Analysis of Composites for Water Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Melody Ghaderidosst; Vilma Hurtigh Grabe; Rebecka Norman; Adam Rosvall; Evelina Wiksten; [2021]
    Keywords : Tunnel Modeling; Water Applications; Composites; Natural Fibers; Polymers;

    Abstract : Hydroelectric power is a leading source of renewable energy where large turbines convert the kinetic energy of water into electricity. In order to not exceed the capacity limit of the turbine, excess water in the dams needs to be diverted away through spillways. READ MORE
