  1. 21. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

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

    Författare :Emil Vejlens; Dylan De Jourday; [2022]
    Nyckelord :Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

    Sammanfattning : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. LÄS MER

  3. 22. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
    Nyckelord :CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

    Sammanfattning : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. LÄS MER

  4. 23. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Linda Péroux; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. LÄS MER

  5. 24. INFLUENCE OF COOLING METHODS ON THE ENERGY DENSITY OF BATTERIES : Comparing different cooling methods for Lithium-ion batteries

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Oscar Söderberg; Simon Norberg; [2022]
    Nyckelord :Lithium-ion batteries; Battery thermal management system; NCA; Cylindrical battery cell; C-rates; CFD; Energy density.;

    Sammanfattning : Due to climate change, the energy system needs to change from traditional fossil fuels to be dominated by renewable energy sources. Not only the energy system, but the increasing number of vehicles and emissions from the transport sector are a problem for climate change and that need to be solved. LÄS MER

  7. 25. Scale up of a test fluid for testing the fuel system robustness against soft particles in biodiesels

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Romain Couval; [2021]
    Nyckelord :biodiesel; soft particles; fuel system; scale up; test fluid; drop-in fuels;

    Sammanfattning : The future of fuels will most probably be a mixture of different fuels, called drop-in fuels. It is already known that these drop-in fuels will lead to solubility issues, with creation of deposit on crucial fuel system parts, due to the formation of soft particles. The fuel system of the future should be robust against any type of soft particles. LÄS MER
