    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  3. 2. Exploratory study of additively manufactured heat exchangers for aerospace applications

    Master-uppsats,

    Författare :Siddharth Nadukkandy; [2023]
    Nyckelord :;

    Sammanfattning : Thermal management is a crucial part in the aviation industry. It is also essential that the components involved in aviation be light weight. One of the vital components of thermal management is heat exchangers. It has been observed that the optimization of the heat exchanger is approaching its saturation with traditional manufacturing.

  4. 3. En studie av TPMS-baserade nätverksstrukturer tillverkade i PA11 : A study of TPMS-based network structures made in PA11

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Johan Sundbom; Jakob Delahunt; [2023]
    Nyckelord :Triply Periodic Minimal Surfaces TPMS ; Gyroid structure; material testing; FEA; compression test; Triply Periodic Minimal Surfaces TPMS ; gyroidstruktur; materialprovning; FEM; kompressionsprov;

    Sammanfattning : SammanfattningTriply Periodic Minimal Surface (TPMS)-baserade nätverksstrukturer har snabbt blivit populära i flera tillämpningar, exempelvis medicinska implantat, värmeväxlare, stötdämpareoch lättviktskonstruktioner. Gyroidstrukturen är förmodligen den mest kända och använda, men en mängd varianter existerar med extremt goda egenskaper vid additiv tillverkning. LÄS MER

  5. 4. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :María Xuan Celaya Granados; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  7. 5. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Författare :Jordis Hansen; [2023]
    Nyckelord :XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Sammanfattning : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. LÄS MER
