  2. 2. Modeling and Control of a PMSynRel Drive for a Plug-InHybrid Electric Vehicle

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Shuang Zhao; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; feasible region; inductance spatial harmonics; integrated charger; permanent-magnet assisted synchronous reluctance machine; plug-in hybrid-electric vehicle; polarity detection; saturation and cross-saturation; sensorless control; signal injection; transient modeling.;

    Sammanfattning : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. LÄS MER

  3. 3. Steam condensation in a water pool and its effect on thermal stratification and mixing

    Detta är en avhandling från Sweden : KTH Royal Institute of Technology

    Författare :Ignacio Gallego-Marcos; KTH.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam injection; EHS EMS; blowdown pipes; spargers; chugging; oscillatory bubble; CFD; condensation pool; stratification; mixing; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The Pressure Suppression Pool (PSP) of a Boiling Water Reactor (BWR) is a large heat sink designed to limit the containment pressure by condensing steam released from the primary coolant system. The development of thermal stratification is a safety concern since it leads to higher containment pressures than in completely mixed conditions, and can affect the performance of systems such as the emergency core cooling and containment spray, which the use PSP as a source of water.

  4. 4. Co-injection of basic fluxes or BF flue dust with PC into a BF charged with 100% pellets effects on slag formation and coal combustion

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Lena Sundqvist Ökvist; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Based on 100% pellets operation at BF No. 3 at SSAB Tunnplåt in Luleå a new pellet with CaO/SiO2=1 was developed during early nineties. The pellet showed good results in metallurgical laboratory test but caused slag formation problems in the bosh. LÄS MER

  5. 5. Studies on Diesel sprays under non-reacting and reacting conditions

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Chengjun Du; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion flame; OH radical; ethanol; spray vaporization; soot formation; cavitation; turbulent; OH* chemiluminescence; laser extinction; LAS; Diesel sprays;

    Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER
