1. One-Dimensional Velocity Distributions of Fast Ions under RF Heating Including Doppler Shift in Tokamaks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The goal of nuclear fusion research is to create a clean and virtually limitless energy source. In order to that, a plasma must be heated to hundreds of millions degrees Celsius. A commonly used heating mechanism is ion cyclotron resonance heating, where antennas emit radio waves into the plasma. LÄS MER
2. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Axial flux induction machines are attractive solutions for electric vehicle applications nowadays. Thanks to their high torque density and no need for rare-earth material for permanent magnets, axial flux induction machines are the most used electric machine type with good performance and low prices.

3. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. LÄS MER
4. Regression Models of 3D Wakes for Propellers
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : In this work, regression models for the wake field entering a propeller at certain axial andnominal position have been proposed. Wakes are non-uniform flows following a body immersedin a viscous fluid. We have proposed models for the axial and tangential velocity distribution asfunctions of ship hull and propeller measures.

5. CFD-BERÄKNING AV INSTRÖMNING TILL ETT VATTENKRAFTVERK : –EN FALLSTUDIE AV FINNFORS KRAFTVERK
Master-uppsats, KTH/VattendragsteknikSammanfattning : I Sveriges kalla klimat innebär isrelaterade problem årliga produktionsförluster för vattenkraftföretagen. Kravisbildning på intagsgrinden till ett vattenkraftverk betyder att den grindarea genom vilken vatten kan strömma in reduceras och inströmningsförlusterna ökar. LÄS MER
