  3. 22. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : María Xuan Celaya Granados; [2023]
    Keywords : ;

    Abstract : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. READ MORE

  4. 23. Thermal Analysis of Tap- Changers

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Daniel Lundberg; [2023]
    Keywords : Thermal analysis; COMSOL; tap-changers; heat transfer;

    Abstract : This thesis provides a way of mapping the temperature development of the tap-changer oil for some different standardized loading cases. The project was in collaboration with Hitachi Energy for one of their production cites situated in Ludvika, Sweden. The software used for the simulation environment was COMSOL 6.1 which is a finite element solver. READ MORE
