Comparison of continuum models using the kinetic theory of granular flow with discrete particle models and experiments: extent of particle mixing induced by bubbles
Bokkers, G.A. and Sint Annaland van, M. and Kuipers, J.A.M. (2004) Comparison of continuum models using the kinetic theory of granular flow with discrete particle models and experiments: extent of particle mixing induced by bubbles. In: Proceedings of Fluidization XI.
|Abstract:||The bubble formation and extent of particle mixing induced by a single bubble injected in a mono-disperse uidised bed at incipient
uidisation conditions has been studied with a Two-Fluid continuum Model (TFM) using the Kinetic Theory of Granular Flow (KTGF) and com-
pared with experiments and simulation results obtained from a Discrete Particle Model (DPM). The eect of dierent gas-particle drag models and frictional viscosity models on the bubble behaviour and extent of particle mixing has been assessed. To describe the extent of particle
mixing well, a frictional viscosity model needs to be included, however, the currently available frictional viscosity models need further improvement.
