  1. 1. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

    Författare :Eva Ståhl Wernersson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

    Sammanfattning : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. LÄS MER

  2. 2. Mixing patterns in Rushton-turbine-agitated reactors

    Författare :Fabrice Guillard; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; coherent mixing structure; geometrical analysis; dynamic structural analysis; conditional sampling; laser-induced fluorescence; mixing; stirred tank; Livsmedelsteknik;

    Sammanfattning : This Ph.D. Thesis concerns the study of mixing in Rushton turbine agitated reactors. In industrial (bio)reactors, mixing is recognised as a limiting factor that significantly affects the performance of the process. LÄS MER

  3. 3. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks

    Författare :Ziyun Yu; KTH; []
    Nyckelord :hydrodynamics; stirred tank; phase Doppler anemometer;

    Sammanfattning : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. LÄS MER
