Abstract
An air stream is injected into a packed bed immersed in water. The refractive index of the water and the packed bed is closely matched; yet, the edges of the spherical particles can be seen. Two distinctive regimens can be observed. The first one, for low air flow rates, is characterized by the percolation of the air through the interstitial spaces among particles, which remain fixed in space. The second one, for high air flow rates, is characterized by the accumulation of air inside the packed bed without percolation; in this case the bubble causes significant agitation of the surrounding particles.
