  1. 6. Quantum Simulation of Quantum Effects in Sub-10-nm Transistor Technologies

    University essay from Uppsala universitet/Materialteori

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

    Abstract : 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. READ MORE

  3. 7. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mahim Ahsan; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 8. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    University essay from KTH/Fysik

    Author : Yuer Zhao; [2021]
    Keywords : 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;

    Abstract : 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). READ MORE

  5. 9. Simplification of CAD Geometries to perform CEM Simulations

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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. READ MORE

  6. 10. Investigating the Impact of Water Injection on Noise Generation During Rocket Lift-Off

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sångberg Linus; [2021]
    Keywords : Rocket lift-off; Turbulent mixing noise; CFD;

    Abstract : This thesis aim to provide SSC, Swedish Space Corporation, with a foundation for understanding the key ideas behind water injection during rocket lift-off, including problems to be avoided when simulating the phenomena. This investigation focus on finding approaches suitable for obtaining a rough estimate of the reduction in noise generation, when too expensive equipment required is absent. READ MORE
