The geometry of the spout, the local bed voidage, and the maps of velocities and trajectories of the particles have been studied in conical spouted beds by means of a probe composed of three optical fibers placed in parallel. The overall analysis of these properties allows for understanding solid circulation in the contactor and at the interface between the annular and spout interface. The influence on the local properties of the geometric factors of the contactor (angle and inlet diameter) and of the operating conditions (diameter of the glass spheres, stagnant bed height, - and excess of air velocity above that corresponding to the minimum spouting) has been studied. The results are interesting for a rigorous modeling of gas and solid flow in the contactor.
