Abstrakt

This work concerns a experimental and numerical study on how the amount of particles influences the flow in the CFB. Experiments are performed with a 1D Laser and Phase doppler anemometry, whereby data of axial velocity, RMS velocity and particle diameter is obtained. The numerical simulations are based on a Multiphase Computational Fluid Dynamics code, where the conservation equations for the solid phases are based on the kinetic theory of granular flow. The experimental data is used to evaluate the multiphase CFD code with alternative gas-solid drag models, which showed an improved agreement with the experimental findings.
