  1. 11. Design and numerical analysis of an overflow section : a case study of Longtan dam

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Albin Wessling; Simon Jonsson; [2018]
    Keywords : Overflow section; design; FEM; stability;

    Abstract : This thesis covers the master diploma work conducted at Hohai University, Nanjing, People's Republic of China. An overflow spillway section fitted for the Longtan Dam was designed and the loads acting on it was identified after an iterative flood routing calculation. READ MORE

  3. 12. Structural intrusion, flow disturbance and spillway capacity : CFD modeling of the Torpshammar dam

    University essay from Uppsala universitet/Elektricitetslära

    Author : Adéle Wallin; [2018]
    Keywords : RNG k-ε model; VOF; Fluent; turbulence; rectangular beams; flow pattern; discharge capacity; flow velocity;

    Abstract : At the Torpshammar dam two rectangular beams are situated upstream of the spillway gates to stabilize the sidewalls holding the embankment of the dam. A computational fluid dynamics (CFD) simulation of the dam with the bottom outlets open was made to investigate how the flow and discharge capacity is affected by the beams. READ MORE

  4. 13. 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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Anders Ramqvist; Martin Länsmans; [2017]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 14. Layout of spillway aerator air ventsand its effect on air supply

    University essay from KTH/Mekanik

    Author : Gustav Daggenfelt; [2017]
    Keywords : ;

    Abstract : Chute aerators are constructed to protect spillways from cavitation damage.They function by launching the water ow as a jet and supplying airunderneath since having air entrained into the water is an eective way tomitigate cavitation. READ MORE

  6. 15. CFD modelling of ski-jump spillway in Stornnforsen

    University essay from KTH/Marina system

    Author : Simon Eklund; [2017]
    Keywords : ;

    Abstract : Traditionally when designing dams and spillways, experiments in physical scale models are conductedin order to determine whether or not the design fulls it purpose, and to identify and avoid undesiredproblems, such as unfavourable ow patterns and unwanted water splatter. Physical models can oftenbe expensive and time consuming to build, and often suer from scale eects that in uence the results. READ MORE
