  1. 1. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Gustav Blomgren; Ebba Carlsson; [2023]
    Nyckelord :Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Sammanfattning : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. LÄS MER

  3. 2. The impact of addition of force control agent in adhesive mixtures : Effect of magnesium stearates on flowability and aerosolization properties

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Författare :Moa Erlandsson; [2023]
    Nyckelord :;

    Sammanfattning : When drugs need to be delivered to the respiratory system dry powder inhalers (DPIs) are often used. The powders in DPIs often consists of a micronized active pharmaceutical ingredient (API) that is adhered to a larger carrier particle forming an adhesive mixture. LÄS MER

  4. 3. CFD Analysis of the Flow Around a Paraglider Wing

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Caterina Gennari; [2023]
    Nyckelord :Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

    Sammanfattning : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. LÄS MER

  5. 4. The Mediating Role of Social Trust. A Quantitative Study of Frequent Social Interaction and Attitudes toward Immigrants.

    Kandidat-uppsats, Malmö universitet/Institutionen för globala politiska studier (GPS)

    Författare :Fatima Fridh; [2023]
    Nyckelord :attitudes toward immigrants; social trust; immigrants; contact theory; frequent social interaction.;

    Sammanfattning : One of the pillars of a democratic society is social trust. It strengthens the perception of group values and creates a social environment that may influence attitudes toward immigrants. This paper delves into the dynamics of frequent social interaction (FSI), attitudes towards immigrants (ATI), and the mediating role of social trust (ST). LÄS MER

  7. 5. A comparison of pressurised cylinders in HIP systems using CFD and FEM

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

    Författare :Lisa Lindqvist; [2021]
    Nyckelord :Hot isostatic pressing; HIP; Pressure vessel; Monoblock; Axisymmetric; FSI;

    Sammanfattning : A hot isostatic press (HIP) is a system which utilises high temperatures and pressure in order to densifyand enhance the material properties of components in the aerospace, automotive and additive manufacturingindustries, to mention a few. Quintus is a world leading manufacturer of HIP systems, and this master’s thesiswork has been written in collaboration with them. LÄS MER
