  1. 6. Viability, feasibility and Sustainability of emission reducing solutions for Nordic wood stoves: Testing and evaluation : Degree project for Master in mechanical engineering with focus on innovative and sustainable product development

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Casper Berg; [2022]
    Nyckelord :Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

    Sammanfattning : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.

  3. 7. Quantum Simulation of Quantum Effects in Sub-10-nm Transistor Technologies

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialteori

    Författare :Anders Winka; [2022]
    Nyckelord :Transistor Modeling; Quantum Transport; QTBM; Block Cyclic Reduction; Quantum Computing; Quantum Annealer;

    Sammanfattning : In this master thesis, a 2D device simulator run on a hybrid classical-quantum computer was developed. The simulator was developed to treat statistical quantum effects such as quantum tunneling and quantum confinement in nanoscale transistors. LÄS MER

  4. 8. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car

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

    Författare :Mahim Ahsan; [2021]
    Nyckelord :;

    Sammanfattning : The importance of aerodynamics in racing has increased substantially over the past decades. Racing vehicles utilize different aerodynamic devices, to redirect the airflow around the vehicle in a beneficial way. The increase in downforce using an aerodynamic wing package increases drag force. LÄS MER

  5. 9. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    Master-uppsats, KTH/Fysik

    Författare :Yuer Zhao; [2021]
    Nyckelord :In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Sammanfattning : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). LÄS MER

  7. 10. Simplification of CAD Geometries to perform CEM Simulations

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Farrukh Bashir; [2021]
    Nyckelord :Defeaturing; Modification; Blending Features; FEA; CEM; CAD; CAE.;

    Sammanfattning : The purpose of this study is to investigate small features in CAD geometries which have high influence on computational time and memory consumption during electromagnetic simulations using CAE software. Computational Electromagnetics (CEM) simulations of complex CAD geometries like passenger cars crash often simulations remain incomplete due to a lot of irrelevant details. LÄS MER
