  4. 23. A study of bubble behaviors in a liquid steel bath

    Författare :Yonggui Xu; Mikael Ersson; Pär Jönsson; Dongyuan Sheng; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The fundamental aspects of rising argon bubbles in molten metal flow were investigated by numerical simulations. The process of a bubble rising in the molten metal includes two steps, one is the bubble rising inside the liquid, and the other one is the bubble rising across the liquid surface. LÄS MER

  5. 24. Downstream migration of salmonids in regulated rivers : Non-conventional methods for fish diversion

    Författare :Johan Leander; Jonatan Klaminder; Micael Jonsson; Gustav Hellström; Paul Kemp; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fish migration; Fish passage; Fish guidance; Hydropower; Atlantic salmon; Brown trout; Bubble barrier; Non-physical barrier;

    Sammanfattning : Passages through hydropower plants can be fatal for downstream migrating salmonids (Salmo spp.). This is particularly true for large adults that are returning to the ocean after spawning. LÄS MER

  7. 25. Growth and Removal of Inclusions During Ladle Stirring

    Författare :Mats Söder; KTH; []
    Nyckelord :inclusions; ladle; gas-stirring; induction-stirring; secondary refining; bubble flotation;

    Sammanfattning : The growth and removal of inclusions in stirred ladles hasbeen studied. First, the importance of different growthmechanisms suggested in the literature were studied. Simulationresults from a fundamental model of an induction-stirred ladlehave been used as input in the calculations. LÄS MER
