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

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

    Author : Marcus Pettersson; [2019]
    Keywords : ;

    Abstract : 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.

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

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

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

    Abstract : 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.

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

    University essay from Lunds universitet/Industriell elektroteknik och automation

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

    Abstract : 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. READ MORE

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

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

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

    Abstract : 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. READ MORE

  5. 5. Thermal Analysis of a Sea Wave Generator

    University essay from KTH/Elkraftteknik

    Author : Ezequiel Quijada; [2017]
    Keywords : sea wave power generator; magnet overheating; demagnetization; heat transfer; conjugate heat transfer; thermal resistance; Comsol Multiphysics; cooling technique;

    Abstract : Wave power has been increasing the interest of many researchers looking for alternative sustainable energy sources since the reserves have proved to be capable of satisfying a considerable percentage of the world´s energy demands. This option has not been adopted as a sustainable source since there are some challenges in the process of designing a low cost device that converts the kinetic energy of the waves into electric energy and that could still be efficient enough to be competitive against other options.
