1. 1. 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

3. 2. Quality and trust in physical model test : Examination by CFD modelling

   University essay from

   Author : Erik Kempe; [2022]
   Keywords : ;

   Abstract : Many of the hydropower dams in Sweden need to be refurbished in order to be able to handle higer design floods. A part of the work in refurbishing the dams is to build physical models. When the physical models are built the uppstream reservoir area is designed to be a couple of times wider and longer than the spillway. READ MORE

4. 3. The future of Hästbergadammen - Restoration and re-purposing of an abandoned hydroelectric powerplant

   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Nina Allberg; [2021]
   Keywords : Arts and Architecture;

   Abstract : This thesis work is an academic study investigating how to transform and re-purpose the abandoned hydroelectric powerplant, Hästbergadammen. The powerplant has been abandoned since the dam collapsed in 2010, and the case of rebuilding it has been in the Land and Environment Court since 2016. The thesis proposes a new purpose for the site.

5. 4. CFD Simulations of Flow Characteristics of a Piano Key Weir Spillway

   University essay from Uppsala universitet/Elektricitetslära

   Author : William Sjösten; Victor Vadling; [2020]
   Keywords : Piano Key Weir; Ansys Fluent; Multiphase Flow; Spillway; Flow Characteristics; CFD; Realizable k-epsilon; Volume of Fluid; Renolds-averaged Navier-Stokes;

   Abstract : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. READ MORE

6. 5. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

   University essay from Uppsala universitet/Elektricitetslära

   Author : Micaela Hamberg; Signe Dahlin; [2019]
   Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

   Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE
