  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. Thermal Analysis of Wave Energy Converter : Developing a Compact CHT Model for Operational Insights

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jakob Jidbratt; Joel Leckström; [2023]
    Nyckelord :Computational Fluid Dynamics; CFD; Conjugate Heat Transfer; CHT; Wave Energy Converter; WEC; Moving mesh; Ball screw;

    Sammanfattning : Climate change is a critical global issue that continues to shape the way we understand and interact with the world around us. It is discussed more than ever before, especially in politics. LÄS MER

  4. 3. Rocket Jet Impinging on a Surface

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Javier Capel Jorquera; [2022]
    Nyckelord :Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Sammanfattning : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. LÄS MER

  5. 4. Verification of the fluid dynamics modules of the multiphysics simulation framework MOOSE : A work to test a candidate software for molten salt reactor analysis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Erik Gustafsson; [2022]
    Nyckelord :molten salt reactor MSR ; small modular reactor SMR ; computational fluid dynamics CFD ; multiphysics; MOOSE;

    Sammanfattning : This is a report of a verification study of the multiphysics simulation framework MOOSE which was preformed at the company Seaborg Technologies. In the process of designing molten salt reactors there is a special need of making credible multiphysics simulations since the fuel is in motion. LÄS MER

  7. 5. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Soumen Ghosh; [2022]
    Nyckelord :Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Sammanfattning : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. LÄS MER
