  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  3. 2. Conjugate Heat Transfer Analysis of HPGP Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. LÄS MER

  4. 3. Groundwater Modelling in southeast Cambodia - Facing irrigation and groundwater level changes during a pandemic

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Svea Bertolatus; [2024]
    Nyckelord :Cambodia; GMS Modflow; Groundwater modelling; irrigation; Mekong; Prey Veng; Svay Rieng; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : In the Mekong region, sustainable water resource management is a significant challenge for all countries involved. In Cambodia, where rice production is crucial for household food security and export, groundwater is increasingly used for irrigation during the dry season, leading to higher rice yields. LÄS MER

  5. 4. Parameteridentifikation för matematisk modell beskrivande tumörcellers och makrofagers interaktioner

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Jonatan Bertolozzi; Regina Gustavsson; Karl Olsson-Lalor; Ellinor Svenningsson; [2023-11-28]
    Nyckelord :;

    Sammanfattning : Det finns sedan tidigare en mängd matematiska modeller som beskriver tumörcellers tillväxt och interaktioner med makrofager i kroppen. I projektet studerades en av dessa vilken beskriver tillväxtförloppet av malignt melanom i möss. Modellen innehåller ett antal parametrar varav några är oidentifierade. LÄS MER
