    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Victoria Done; [2014]
    Keywords : substation; environmental compliance; transformer oil; oil separation; oil handling; ställverk; miljösäkring; transformatorolja; oljeavskiljning; oljehantering;

    Abstract : Svenska kraftnät is the Swedish transmission system operator, responsible for the national electrical grid with power lines of 220 kV and 400 kV, and the electrical substations of the grid. In this master thesis an old substation located in a sensitive environmental area is inspected and its environmental risks defined and assessed. READ MORE

  3. 7. CFD simulation of pool dynamics in a nuclear reactor's condensation pool

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Anders Jansson; [2014]
    Keywords : CFD; computational fluid dynamics; condensation pool; pool dynamics; nuclear reactor; CFD; beräkningsströmningsdynamik; kondensationsbassäng; pooldynamik; kärnkraftsreaktor;

    Abstract : In a nuclear reactor the containment protects the environment from radioactive emissions. It is separated in two parts, a drywell and a wetwell. The drywell contains the reactor vessel and the steam pipes. If a steam leakage occurs in this part of the containment the pressure will increase. READ MORE

  4. 8. A pre-study on the compressed air system at Ljunghaell AB

    University essay from Högskolan i Halmstad/Sektionen för ekonomi och teknik (SET)

    Author : Joakim Nelson Berg; Jonathan Lee; [2014]
    Keywords : Compressed air system; energy efficiency; operation; compressor; pipe system and leak detection; Tryckluftssystem; energieffektivisering; drift; kompressor; rörsystem samt läckagesökning;

    Abstract : The Swedish industry uses large volumes of compressed air. The compressed air process isenergy intensive and creates large amounts of excess heat. It is therefore important to utilizethe excess heat, optimize the operation of the compressors and to have a regular maintenanceon the system. READ MORE

  5. 9. Analytical and Numerical Analysis of the Acoustics of Shallow Flow Reversal Chambers

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Alireza Qazizadeh; [2012]
    Keywords : ;

    Abstract : Flow reversal chambers are mainly used to accomplish a compact silencer design needed on a vehicle. Generally in this configuration the inlet and outlet ports are on the same face and the flow direction is reversed. READ MORE

  6. 10. Measurement of Blowby in a Turbocharger

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Jonny Tuominen; [2007]
    Keywords : ;

    Abstract : The purpose with this Masters Thesis was to design a measurement rig for measurement of the blowby flow that originates from the turbocharger in a passenger car engine. A leakage of com-bustion gases and fresh air from the turbine and the compressor into the bearing housing of the turbocharger is the source of the blowby flow. READ MORE
