  1. 1. A Simulation of Landslide-Generated Waves Using a Fully Implicit ISPH

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Kosei Nishida; [2020]
    Nyckelord :SPH; Landslide-generated waves; non-newtonian fluid; multiphase flow; Technology and Engineering;

    Sammanfattning : Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. LÄS MER

  3. 3. 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. 4. CFD and Experimental Study of Refuelling and Venting a Fuel System

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära;

    Författare :Aditya Naronikar; Anton Riström; [2019]
    Nyckelord :CFD; VOF; multiphase; refuelling; gasoline; ORVR; automotive; volvo;

    Sammanfattning : In 1999, California Air Resources Board (CARB) implemented a regulation that required all gasoline cars sold in California be fitted with an Onboard Refueling Vapor Recovery System (ORVR). The ORVR system is designed to prevent Volatile Organic Compounds (VOCs) from escaping into the atmosphere during refuelling by storing the gas vapours in a carbon canister. LÄS MER

  5. 5. CFD Simulation of Fluid Flow During Laser Metal Wire Deposition using OpenFOAM : 3D printing

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

    Författare :Jennifer Lundkvist; [2019]
    Nyckelord :;

    Sammanfattning : The focus of this work was to simulate the fluid flow within a melt pool geometry, during an additive manufacturing process, implementing the CFD software OpenFOAM version 1806. Two separate models were created and run during this work, the first using a temperature mapping from a finite element (FE) model and the second being a free-standing model with Gaussian distributed laser beam striking down on the top surface.
