  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. Rocket Jet Impinging on a Surface

    University essay from KTH/Teknisk mekanik

    Author : Javier Capel Jorquera; [2022]
    Keywords : Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Abstract : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. READ MORE

  5. 4. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    University essay from KTH/Fysik

    Author : Yuer Zhao; [2021]
    Keywords : In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Abstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE

  6. 5. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jonathan Barassa; Rickard Nordlöf; [2020]
    Keywords : Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

    Abstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE
