    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.

  2. 2. Cooling Potential of Methane in Rocket Nozzle Cooling Channels : A Conjugate Heat Transfer Analysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Pettersson; [2019]
    Nyckelord :;

    Sammanfattning : The use of hydrocarbons as fuel in rocket propulsion has been of great interest to the aerospace industry in recent years. Specifically, natural gas with a high content of methane has taken the interest of several actors, among them Sweden-based GKN Aerospace who in collaboration with KTH Royal Institute of Technology have started the MERiT project.

  3. 3. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hamidreza Rastan; [2019]
    Nyckelord :Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Sammanfattning : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  4. 4. Directly Cooled Windings - Conjugate heat transfer assessment of air-cooled hollow conductor

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Michael Gabassi; [2018]
    Nyckelord :Conjugate heat transfer; hollow conductor; thermal management; direct cooled windings; heat transfer; electrical machines; Technology and Engineering;

    Sammanfattning : The torque capabilities of electrical machines are today limited by magnetic saturation and the ability to transfer thermal loads away from the machine. A solution to thermal management in power turbo-generators involves hollow conductors allowing direct cooling of the heat source thus increasing the power density significantly. LÄS MER

  5. 5. Compressor CFD simulation method development : A CFD study

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan Björk; [2018]
    Nyckelord :CFD; centrifugal compressor; CFX; CHT; Conjugate Heat Transfer; Surge;

    Sammanfattning : This master thesis project consisted of three parts that all were performed through CFD simulations with the purpose to develop Scania's methods in the subject of CFD. All parts included simulations on Scania's SC92T70 centrifugal compressor. LÄS MER
