  3. 2. 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

  4. 3. Flow and turbulence in the discharge stream of different agitators for stirred tanks

    Författare :Tamás Kovács; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluiddynamik; Gaser; plasmas; fluid dynamics; Gases; Livsmedelsteknik; Food and drink technology; Scaba; 6SRGT; pseudo turbulence; Rushton; stirred tank; plasma; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : In this thesis, the fluid dynamic properties of the conventional Rushton turbine and another impeller type, the Scaba Radial flow Gas dispersing Turbine (with six concave blades) are compared. For comparison, point-wise velocity measurements were made in the discharge of the two turbine types using Hot-Wire Anemometry in constant temperature mode (CTA) with a split film probe. LÄS MER

  5. 4. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems

    Författare :Fredrik Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry PIV ; single-phase; Laser Doppler Anemometry LDA ; mixing; liquid-Liquid; immiscible; stirred tank; Rushton turbine; Computational Fluid Dynamics CFD ; macro-instability; frequency analysis; refraction index matched;

    Sammanfattning : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. LÄS MER
