1. 21. How Odd is Betelgeuse?

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Martin Oshaughnessy; [2020]
   Nyckelord :Betelgeuse; runaway stars; stellar evolution; binary interactions; Physics and Astronomy;

   Sammanfattning : The role of massive stars (those with masses greater than eight solar masses) in the chemical enrichment of galaxies and renewed star formation forms an important field of fundamental research in modern astrophysics. The complex nature of massive star evolution produces formidable challenges in furthering our understanding of the processes driving massive star evolution. LÄS MER

3. 22. Distribution of bed material in a Horizontal Circulating Fluidised Bed boiler

   H-uppsats,

   Författare :Thomas Ekvall; Robin Magnusson; [2019-07-03]
   Nyckelord :Energi; Hållbar utveckling; Energiteknik; Miljöteknik; Energy; Sustainable Development; Energy Engineering; Environmental engineering;

   Sammanfattning : A conventional circulating fluidised bed (CFB) boiler has a limitation due to the height of the furnace, when implemented in smaller industrial facilities. The design of a horizontal circulating fluidised bed (HCFB) boiler is an interesting approach to resolve this problem. LÄS MER

4. 23. Experimental and CFD Study of Heat Pickup in Cooling System Hoses

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :August Borg; Michael Owen; [2019]
   Nyckelord :;

   Sammanfattning : This thesis investigates a process known as heat pickup which occurs in vehicle cooling system hoses. Heat pickup is an unwanted side effect of temperature differences in a car underhood compartment, whereby excess heat is tranferred into the coolant running through the cooling system hoses, affecting its operating temperature.

5. 24. Quenching a steel plate by water - impinging jets and different simultaneous flow rates

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Pablo Martinez; [2019]
   Nyckelord :Quenching; steel; plate; cooling; water- impinging jets; cooling rate; subcooling; temperature.;

   Sammanfattning : Regarding the great importance of fast cooling in steel industry for the production processes, a deep understanding of heat transfer and fluid dynamics must be held. A steel plate is heated up until a maximum temperature of 700 ⁰ C to be the n cooled down seconds later by a configuration of multi ple impinging water jets. LÄS MER

7. 25. Modeling of a Gear Test Rig : An Investigation of Static Loads and Dynamic Excitation of Vibrations

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Albin Hugoh; [2019]
   Nyckelord :;

   Sammanfattning : Today the automotive industry is going through big changes and facing many new challenges due to the transformation to a sustainable transport solution in combination with tougher legal demands. Gears have been around for a long time and it is one of the most efficient ways of transferring rotary motion from one shaft to another. LÄS MER
