  1. 21. Motion of a Gaussian Through a 2D Dilute BEC Droplet

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Zhanna Kuhrij; [2020]
    Nyckelord :Bose-Einstein Condensate; BEC; Droplet; Dilute; Liquid; Quantum Mechanics; Fluid Dynamics; Superfluid; Superfluidity; Quantum Fluctuations; LHY-correction; Flow patterns; Gaussian; 2D; Vortices; Gross-Pitaevskii Equation; Physics and Astronomy;

    Sammanfattning : In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. LÄS MER

  3. 22. 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

  4. 23. Next generation expedition stove : A lead user approach to product development

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Frida Rybo; Alfred Söder; [2020]
    Nyckelord :Outdoor equipment; lead user approach; Gioia methodology; expedition; stove; Friluftsutrustning; lead user; Gioia; expedition; friluftskök;

    Sammanfattning : In 1996 Primus launched their expedition stove Multifuel, the first stove that could run on liquified petroleum gas (LPG), white gas, kerosene and aviation fuel. The multi-fuel stoves are part of the Primus expedition range of equipment. The line was designed and built to perform in extreme conditions. LÄS MER

  5. 24. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

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

    Författare :Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Nyckelord :;

    Sammanfattning : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. LÄS MER

  7. 25. Ventilation av inomhusskjutbanor

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Eric Bergman; Emma Gahne; [2019]
    Nyckelord :Firing; Shooting; Range; Small arms; Guns; Ventilation; CFD-simulations; Lead; Anania; Skjutbana; Vapen; Skytte; Luftföroreningar; Bly; Ventilation; Anania;

    Sammanfattning : Skytte med eldhandvapen skapar buller, utsläpp av farliga ämnen och risk för att avlossade projektiler missar sina mål och istället hamnar utanför skjutbanan. Att förlägga skjutbanor inomhus löser vissa av dessa problem. Samtidigt kan risken för att utsättas för farliga ämnen öka för dem som brukar skjutbanan. LÄS MER
