  1. 1. Thermal Analysis of Wave Energy Converter : Developing a Compact CHT Model for Operational Insights

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jakob Jidbratt; Joel Leckström; [2023]
    Nyckelord :Computational Fluid Dynamics; CFD; Conjugate Heat Transfer; CHT; Wave Energy Converter; WEC; Moving mesh; Ball screw;

    Sammanfattning : Climate change is a critical global issue that continues to shape the way we understand and interact with the world around us. It is discussed more than ever before, especially in politics. LÄS MER

  3. 2. Wading Simulations of Complete Heavy-Duty Vehicles

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

    Författare :Emma Samuelsson; Sofie Benzler; [2022]
    Nyckelord :CFD; Volume of Fluid; Wading; Heavy-Duty Vehicles; STAR-CCM ;

    Sammanfattning : Wading is the phenomenon where a vehicle drives through water with a relatively deep water level. Sincea large portion of the vehicle is submerged in water it can affect the driveability and function of individualcomponents. LÄS MER

  4. 3. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Lea Christierson; [2021]
    Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER

  5. 4. Numerical Simulation of Sabot Discard Projectile

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

    Författare :Karl Karlsson; [2020]
    Nyckelord :CFD; Sabot; Simulation; Fluid Mechanics;

    Sammanfattning : When designing an armour piercing kinetic energy projectile with a discarding sabot, it is important to know how the projectile is affected by the sabot during the discard. If the projectile has no active guiding systems, small disturbances to the initial flight path of the projectile can result in a significant deviance from its intended target. LÄS MER

  7. 5. Computational and experimental study of fuel leakage through a ventilation valve during various driving conditions

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sadegh Fattahi; Philip Månsson; [2019]
    Nyckelord :Sloshing; CFD; MULTIPHASE; fuel tank; volvo; LIU; fuel; ventilation;

    Sammanfattning : Fuel leakage through a fill limit vent valve (FLVV) inside a fuel tank is an important factor to consider during the design of a new tank. The performance of the carbon canister which absorbs the hydrocarbon can be compromised if fuel manages to escape through the valve, so called Liquid Carry Over (LCO) and thus not fulfilling the fuel emission requirements.
