1. 1. One-Dimensional Velocity Distributions of Fast Ions under RF Heating Including Doppler Shift in Tokamaks

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Lukas Bähner; [2022]
   Keywords : plasma; fusion; ICRH; Ion Cyclotron Resonance Heating; RF; radio frequency; Fokker-Planck equation; Fokker-Planck solver; quasilinear operator; Coulomb collision; Doppler shift; velocity distribution; local temperature; plasma; fusion; ICRH; joncyklotronuppvärmning; RF; radiofrekvens; Fokker-Planck-ekvationen; Fokker-Planck-lösare; kvasilinjär operator; Coulombkollisioner; Dopplerskift; hastighetsfördelning; lokal temperatur;

   Abstract : 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. READ MORE

3. 2. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Huanyu Chen; [2022]
   Keywords : CFD simulation; Induction machine; Temperature distribution; Velocity distribution; CFD-simulering; Hastighetsfördelning; Induktionsmaskin; Temperaturfördelning;

   Abstract : 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.

4. 3. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Anna-Maria Söderman; [2022]
   Keywords : star cluster; runaway stars; velocity distribution; Physics and Astronomy;

   Abstract : 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. READ MORE

5. 4. Regression Models of 3D Wakes for Propellers

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Christian Karlsson; [2018]
   Keywords : Propeller design; Wake; Velocity distribution; Regression analysis; Fourier series; Skewed-Gaussians; Coherent structure coloring; Propeller design; Medströmsfält; Hastighetsfördelning; Regressionsanalys; Fourierserier; Skeva-Gaussfördelningar; Koherenta struktureringsfärgmetoden;

   Abstract : 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.
