  1. 6. Efficiency of radial piston hydraulic motors

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jennifer Eriksson; [2023]
    Keywords : Efficiency; Loss mechanics; MATLAB; Simulation model; Radial piston hydraulic motor;

    Abstract : In a world with high energy cost, the efficiency of motors becomes increasingly important. Thereby, the understanding of loss mechanics is of great significance and having accurate simulation models for the efficiency of motors is crucial. READ MORE

  3. 7. Validation of a moderate Reynolds number channel in Neko

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Shicheng Dai; [2023]
    Keywords : Neko; CFD; DNS; Turbulence channel flow;

    Abstract : Neko is a portable framework for high-order spectral element flow simulations[1]. Originally from Nek5000, Neko not only inherited its numerical stability and well-performance, but also added the benefits of dynamic memory and support for many current accelerator backends. READ MORE

  4. 8. Computational Analysis of Spray Deflector Designs

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Osman Gyokhan Ali; [2023]
    Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. READ MORE

  5. 9. Numerical Simulations of Metal Recovery for Battery Recycling

    University essay from KTH/Processteknologi

    Author : Morgan Ölander; [2023]
    Keywords : Batteriåtervinning; Metall återvinning; Kristallisation; Computational Fluid Dynamics CFD ; Populationsbalansmodellering; Battery recycling; Metal recovery; Crystallisation; Computational Fluid Dynamics CFD ; Population balance modelling;

    Abstract : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. READ MORE

  6. 10. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Alexander Elliott Meyer Ströborg; [2022]
    Keywords : low Reynolds number; reflex airfoils; CFD; XFOIL;

    Abstract : Low Reynolds number airfoil analysis has become increasingly significant as urban air mobility vehicles and unmanned aerial vehicles surge in popularity. The Green Raven project at KTH Aero aims to use reflex airfoils where little data is available beyond classical analysis. READ MORE
