The flow pattern in a rotating liquid-solid fluidized bed with particles in the micron range was investigated in the bed and in the freeboard. Simulations of the liquid flow in absence of particles with the CFD-Software CFX 5.7 showed a strong influence of the Coriolis force, which results in high tangential velocities. Experiments in a 1 m diameter rotor confirmed the results of the simulation. The fluidized bed is also moving in the tangential direction. The bed expansion is described by a Richardson-Zaki type correlation.
