  1. 11. CFD Simulation of Urea Evaporation in STAR-CCM+

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Oscar Ottosson; [2019]
    Keywords : Urea; AdBlue; SCR; Solid Deposit; NOx; nitrogen oxides; CFD; speedup; spray simulation; UWS; diesel after-treatment; STAR-CCM ; AVL Fire; Scania; Sweden; NXPS; LiU; DOE; Urea; AdBlue; SCR; Klump; NOx; kvävedioxider CFD; uppsnabbning; spray simulering; UWS; efterbehandling av diesel-motor; STAR-CCM ; AVL Fire; Scania; Sverige; NXPS; LiU; DOE;

    Abstract : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. READ MORE

  3. 12. Investigating Gas Turbulence in Galactic Discs

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Timmy Ejdetjärn; [2019]
    Keywords : galaxies; gas; turbulence; interstellar medium; star formation; feedback; gravitational instability; local; high redshift; Physics and Astronomy;

    Abstract : The interstellar medium of both local and distant disc galaxies is observed to be supersonically turbulent and the turbulent motion of the gas is thought to be important for galaxy formation and evolution, particularly as a key ingredient for star formation. Consequently, this generates a striking relation between the star formation rate (SFR) and gas velocity dispersion ($\sigma_{\rm g}$; a measurement on the level of turbulence). READ MORE

  4. 13. The Gamer Girls of Jorvik : Motivations of Play in Star Stable Online

    University essay from Uppsala universitet/Institutionen för speldesign

    Author : Karoliina Hiidenheimo; Ida Andersson-Junkka; [2018]
    Keywords : Game; MMORPG; Pink; Star Stable; Horses; Girl; Gender; Game Design.;

    Abstract : This thesis examines the motives of play amongst girl gamers aged nine to seventeen. It focuses on the players of the game Star Stable Online also referred to as a ‘pink’ game. It is an empirical study, using a mixed method design. The study is split into two parts and the results from part two were used to support the results from part one. READ MORE

  5. 14. Derivation and stability determination of black hole metrics

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Emma Svensson; [2018]
    Keywords : black holes; relativity; general relativity; kerr metric; schwarzschild metric; derivation; stability; Physics and Astronomy;

    Abstract : The Schwarzschild metric and the Kerr metric describe the gravitational fields around static and rotating black holes, respectively. Here, we derive the Kerr metric in a simpler way than how it was derived originally and determine the stability of the Schwarzschild metric. READ MORE

  6. 15. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

    University essay from KTH/Mekanik

    Author : Emelie Trigell; [2018]
    Keywords : after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

    Abstract : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. READ MORE
