  1. 1. Fluid Dynamics of Fluidized Bed Reactors: Experiments and Simulations with System Interactions

    Författare :Srdjan Sasic; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Air-supply system; Interaction; Fluidized bed; Pressure waves; Pressure fluctuations;

    Sammanfattning : This thesis is a study of the interaction between the fluidized-bed dynamics and the pressure and flow pulsations from the air-supply system. The interaction has been identified as a key process to understand in order to correctly formulate inlet boundary conditions in numerical modelling of fluidized beds, operated under industrial conditions.
