Abstract:To describe the hydrodynamic phenomena prevailing in large industrial scale previous termfluidized bedsnext term continuum models are required. The flow in these systems depends strongly on particle¿particle interaction and gas¿particle interaction. For this reason, proper closure relations for these two interactions are vital for reliable predictions on the basis of continuum models. Gas¿particle interaction can be studied with the use of the lattice Boltzmann model (LBM), while the particle¿particle interaction can suitably be studied with a discrete particle model. In this work it is shown that the discrete particle model, utilizing a LBM based drag model, has the capability to generate insight and eventually closure relations in processes such as mixing, segregation and homogeneous fluidization.
