  1. 6. An Interactive Eye-tracking based Adaptive Lagrangian Water Simulation Using Smoothed Particle Hydrodynamics

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

    Författare :Ajla Elmasdotter; [2020]
    Nyckelord :;

    Sammanfattning : Many water animations and simulations usually depend on time consuming algorithms that create realistic water movement and visualization. However, the intrigue for realistic, real-time and interactive simulations is steadily growing for, among others, the game and Virtual Reality industry. LÄS MER

  3. 7. Flow and Air Quality Modelling of a Car Cabin

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

    Författare :Oskar Jolérus; [2019]
    Nyckelord :CFD; PM2.5; Air quality; Multiphase; LPT;

    Sammanfattning : Adverse health effects attributable to both short- and long-term exposure to air pollution have turned the focus on different microenvironments. The interior of vehicles is of relevance as road traffic emissions and re-suspension of road dust are major sources of pollutants associated with adverse health effects. LÄS MER

  4. 8. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Tetsuro Goda; [2017]
    Nyckelord :Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

    Sammanfattning : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. LÄS MER

  5. 9. Numerical analysis of Urea-SCR sprays under cross-flow conditions

    Master-uppsats, KTH/Mekanik

    Författare :Jakob Heide; [2016]
    Nyckelord :Lagrangian Particle Tracking; Selective Catalyst Reduction; droplet;

    Sammanfattning : The mixing and evaporation of Diesel Exhaust Fluid (DEF) inside an Urea Selective Catalyst Reduction (SCR) chamber has been numerically investigated. The first task in this work has been to first look into the numerical framework and assess the models available in a commercial CFD software (ANSYS Fluent 14.5). LÄS MER

  7. 10. Assessment of numerical integration schemes and boundary conditions for Lagrangian tracking of marine debris

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Kronborg; [2016]
    Nyckelord :Lagrangian tracking; PARCELS; Runge-Kutta; time stepping; boundary conditions; Mathematics and Statistics;

    Sammanfattning : A growing environmental issue today is the amount plastic pollution in the ocean. To investigate how it might affect marine life, an important aspect is to study how plastics are transported by ocean currents and where it ends up. This can be done by use of Lagrangian simulation of plastic particles in computer ocean models. LÄS MER
