  1. 1. Fluid and Solid Particle Dynamics in Stirred Vessels

    Författare :Mattias Ljungqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixing time; pitched blade turbine; impeller modelling; stirred vessels; computational fluid dynamics; multi-fluid model; suspension of solids; phase-Doppler anemometry; laser Doppler anemometry; closed vessels;

    Sammanfattning : The present thesis deals with the fluid dynamics of stirred vessels and particularly those that are to be used in conjunction with solids suspensions. Stirred vessels are very common in the process industry and large amounts of energy can be saved by optimising their operation. LÄS MER

  5. 4. Hydrodynamics and Complete Suspension in Axially Stirred Vessels

    Författare :Claes Sturesson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; axially stirred tank; particle force balances; complete suspension; turbulence modeling; turbulent boundary layer; LDA;

    Sammanfattning : Complete suspension of solid particles in stirred vessels has been subject to numerous investigationsin order to develop appropriate design criteria for solid/liquid suspensions. Previous work on this matter has often suffered from the lack of knowledge of fluid mechanics in the system and models based on overall flow characteristics have been proposed in the literature.
