A numerical model that simulates liquid spray dispersion in the fluidized bed of solid particles is presented. The model includes flow through the atomization device (nozzle), phase inversion and formation of the spray, its interaction with the solid particles, and liquid propagation within the bed. All these processes are modelled simultaneously to reflect the couplings existing between them. The model utilises a Eulerian description for all three phases to allow for the continuous computations throughout the whole domain. The comparison with experimental data reveals reasonably good agreement between the predicted and measured liquid to solid mass ratio distributions.
