  1. 1. Comparison between Smoothed-Particle Hydrodynamics and Position Based Dynamics for real-time water simulation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Rasmus Andersson; Erica Tjernell; [2023]
    Nyckelord :Fluid simulation; Lagrangian fluid simulation; Smoothed-Particle Hydronamics; Position Based Dynamics; Vätskesimulering; Lagransk vätskesimulering; Smoothed-Particle Hydronamics; Position Based Dynamics;

    Sammanfattning : Two of the methods common in video game fluid simulation are SmoothedParticle Hydrodynamics (SPH), and Position Based Dynamics (PBD). They are both Lagrangian methods of fluid simulation. SPH has been used for many years in offline simulations and has truthful visuals, but is not as stable as the newer method PBD when using larger timesteps. LÄS MER

  3. 2. Styrd Fragmentering i Metalliska Stridsdelar : Teknikutveckling av fragmenterande stridsdelar

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :William Persson; Lukas Rehnberg; [2022]
    Nyckelord :Smoothed Particle Hydrodynamics; CAD; Electron Beam Melting; Stridsdel; Additiv tillverkning; AM; Teknikutveckling; Fragment; Granat; Simulering;

    Sammanfattning : Fragmenterande stridsdelar har funnits länge och idag finns tre huvudsakliga metoder för att uppnå fragmentering i en stridsdel. Metoden styrd fragmentering som undersöks i arbetet fungerar generellt sett bra men saknar önskad kontrollförmåga. LÄS MER

  4. 3. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Josep Plana Riu; [2022]
    Nyckelord :;

    Sammanfattning : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. LÄS MER

  5. 4. Stellar Encounters at the Galactic Centre

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Roberts Fisers; [2022]
    Nyckelord :Galaxy; encounter; SPH; NSC; Physics and Astronomy;

    Sammanfattning : Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. LÄS MER

  7. 5. Asymmetries in shaped charges

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

    Författare :Gustav Boman; [2021]
    Nyckelord :;

    Sammanfattning : This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shock­compression results in a jetof metal being shot forward in up 10km/s. LÄS MER
