  2. 1. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study

    Author : Liang Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airflow; Wurster; coating; CFD; particle; Fluidized bed; drying; PEPT; spray; DEM;

    Abstract : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique.

  4. 2. Fluid Dynamics of a Wurster-type Fluidized Bed - A Numerical and Experimental Study

    Author : Anna Magnusson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; optical probe; frictional stress; fluidized bed; Wurster bed; kinetic theory;

    Abstract : The fluid dynamics of a Wurster bed, a fluidized bed used in the pharmaceutical industry for the coating of small particles or pellets, is investigated numerically and experimentally. The main objective of the thesis is to obtain greater knowledge of the flow properties in the Wurster bed. READ MORE

  5. 3. Interaction of flows with slender structures and liquid-infused surfaces

    Author : Johan Sundin; Shervin Bagheri; Daniel Chung; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-structure interactions; flow control; turbulent boundary layers; soft sensors; drag reduction; capillary waves; surfactants; Marangoni stress; mixing enhancement; Engineering Mechanics; Teknisk mekanik;

    Abstract : Surface textures and protrusions can be used to control or gain information about a flow. We investigate the solid-flow interaction of filamentous structures and liquid-infused surfaces (LIS). Both filamentous structures and LIS are used by organisms and can be exploited in technical applications. READ MORE

  6. 4. The fixation of joint prostheses. Aspects on mechanics and biology

    Author : Ulrik Hansson; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; histology; interface; micromotion; knee; joint replacement;

    Abstract : Abstract: In the interface, between implant and bone or between the cement and bone, there will develop some amount of fibrous tissue. The synovial fluid, the synovium, the cartilage and the subchondral bone from the non-replaced knee compartment that had been exposed to wear particles were studied by histological analyses. READ MORE
