  1. 1. Numerical Simulations of Metal Recovery for Battery Recycling

    Master-uppsats, KTH/Processteknologi

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

    Sammanfattning : 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. LÄS MER

  3. 2. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Linnéa Tebelius; [2022]
    Nyckelord :Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Sammanfattning : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.

    Nyckelord :Elasto-inertial microfluidics; particle focusing; particle separation; nanobiotechnology; Elastisk tröghetsmikrofluidik; partikelfokusering; partikelseparation; nanobioteknologi;

    Sammanfattning : The passive particle separation method of elasto-inertial microfluidics have greatpotential in the field of physics, biology and chemistry. The objective of thisdegree project was to understand particle behavior in curved microchannels fornon-Newtonian fluids. LÄS MER

  7. 5. Development of a CFD Boundary Condition to Simulate a Perforated Surface

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

    Författare :Medet Kiflemariam; [2021]
    Nyckelord :Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Sammanfattning : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.
