  5. 19. Experimental study of bubble dynamics and transport

    Författare :Gunilla Andrée; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; Particle Streak Photography; Shadowgraph; Particle Image Velocimetry; Bubble dynamics; bubble transport;

    Sammanfattning : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. LÄS MER

  7. 20. Numerical study of flows related to aerated stirred tanks

    Författare :Dragana Arlov; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluiddynamik; Gaser; plasmas; fluid dynamics; Gases; Lattice Boltzmann method; Volume of Fluid; Aerated stirred tank; Large Eddy Simulation; Eulerian-Lagrangian model; Energy research; Energiforskning; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. LÄS MER
