Due to the interactions between particle - flow, particle - particle and particle - wall, the behavior of solid particles in gas-fluidized beds is very complicated. A number of numerical models have been developed and its expansion to include heat and mass transportation is performed by several researchers at present. These are highly influenced by the dispersion and mixing characteristics of particle and it is important to know the motion of individual particles to develop reliable models. In the present study, a velocity measurement of individual particles is performed in a two-dimensional fluidized bed by using particle tracking velocimetry (PTV). For comparisons, corresponding DEM-CFD coupling simulations is also carried out.
