  1. 1. Propulsion efficiency with energy saving devices for vessels

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Samuel Östlund; [2023]
    Nyckelord :ESD; Energy saving device; Maritime; Kongsberg; Pre-swirl stator;

    Sammanfattning : Due to global warming, all industries must do everything they can to prevent temperature increases. In this bachelor thesis, the reader will get a description of how the marine industry is tackling the environmental problem and more precisely what a vessel can be equipped with to reduce fuel consumption.

  3. 2. Hybrid Simulations of Solar Wind Plasma Interaction with the Lunar Reiner Gamma Magnetic Anomaly

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :David Frisk Strömberg; [2023]
    Nyckelord :;

    Sammanfattning : The Moon has small scale regions of strong magnetic fields scattered over its surface, known as crustal fields. Coexisting with some of the strongest crustal fields are peculiar markings in the lunar soil, called lunar swirls, which are suggested to be formed by magnetosphere-like interactions between the crustal fields and the solar wind plasma.

  4. 3. 3D CFD Simulations of Hydrogen Engine Combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hao Liu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. LÄS MER

  5. 4. Association analyses of forehead hair whorls, behaviour, and chromosome regions in Standardbred Trotters

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Breeding and Genetics

    Författare :Victoria Saxe; [2022]
    Nyckelord :behaviour; temperament trait; tricoglyph; hair whorl; swirl; genetics; horse; Standardbred trotter; genotype; phenotype;

    Sammanfattning : Introduction: In horse breeding, athletic skills have been in focus and certain behaviour types have been found to be important for competition. Behaviour is heritable but is also affected by the environment. Just like humans, animals have their own personality and behaviour-traits. LÄS MER

  7. 5. 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
