  1. 1. Undersökning av ny slamutlastning vid ett reningsverk : Analys av flödesförluster och slampump

    Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Linus Dovnäs; Gustav Edholm; [2022]
    Nyckelord :sludge; sludge pump; sewage; Slam; slampump; reningsverk; flödesförluster; TS-halt; systemkurva; pumpkurva;

    Sammanfattning : A sewage treatment plant is going to get a station in their plant reconstructed. It is the station where the water is separated from the sludge and then transported out of the plant. This new station is the main area for this project. LÄS MER

  3. 2. A Topology-Based Method for Inferring Turbulence in Unsteady Flows

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tobias Edwards; [2021]
    Nyckelord :;

    Sammanfattning : Understanding the rise and evolution of turbulence is an important component of designing vehicles and turbomachinery that both have long life and are efficient. To this end, researchers study the complex phenomenon of turbulence. LÄS MER

  4. 3. Two-dimensional roughness and Tollmien-Schlichting waves: a study on transition

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Derek Micheletto; [2020]
    Nyckelord :;

    Sammanfattning : Two-dimensional (2D) roughnesses induce premature transition to turbulence in laminar boundary layers by amplifying the disturbances in the flow and promoting the development of non-linearities. The present thesis aims at furthering our understanding of this phenomenon's underlying mechanisms and elucidating the effects of the different geometrical parameters of the roughness' cross section.

  5. 4. Demonstration station for open water channel flow

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :David Bayat; Fabian Grönvik; [2020]
    Nyckelord :;

    Sammanfattning : Once a year an event is being held at the fluid physics lab at KTH. One of the main purposes of this event is to awaken an interest in the visiting students from other universities, by demonstrating fluid physics phenomena. Showing the transition from laminar to turbulent flow in an open water channel is one of the demonstrations. LÄS MER

  7. 5. Experimental and CFD Study of Heat Pickup in Cooling System Hoses

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :August Borg; Michael Owen; [2019]
    Nyckelord :;

    Sammanfattning : This thesis investigates a process known as heat pickup which occurs in vehicle cooling system hoses. Heat pickup is an unwanted side effect of temperature differences in a car underhood compartment, whereby excess heat is tranferred into the coolant running through the cooling system hoses, affecting its operating temperature.
