  1. 26. Modeling Dielectric Barrier Discharge plasma actuators to be used for active flow control

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Oscar Eriksson; [2018]
    Keywords : Dielectric Barrier Discharge; plasma; flow control;

    Abstract : This Master Thesis work cover the simulation of the movement of charged species exposed to a high gradient electric field, the same environment a plasma actuator produces. The final goal is to use the plasma actuator as an active flow control device to decrease the drag of a body moving in air. READ MORE

  3. 27. 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. 28. Modeling and control of mill discharge pumps in the Aitik copper mine

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tomas Vikner; [2018]
    Keywords : ;

    Abstract : Boliden Aitik is the largest open-pit copper mine in Sweden, and during 2017, more than 39 million tonnes of ore was processed into concentrated copper, silver and gold. The distributed control system 800xA is provided by ABB, and this is what the operators use for process monitoring and control. READ MORE

  5. 29. Transient modeling of a high temperature borehole thermal energy storage coupled with a combined heat and power plant

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Malin Malmberg; [2017]
    Keywords : ;

    Abstract : Coupling High-Temperature Borehole Thermal Energy Storages (HT-BTES) with existing Combined Heat and Power (CHP) systems is a promising approach to increase energy efficiency of district energy systems through recovery of otherwise wasted heat. This solution is currently being discussed in Sweden by the company Tekniska Verken in Linköping AB, for storing waste heat from their CHP operation in summer in a HT-BTES and to utilize it during peaks in winter.

  6. 30. 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
