Abstract: We have experimentally studied the dense flow of identical bubbles below planes inclined at an angle θ. The flow is driven by the fast motion of dislocations. As a function of the density of dislocations (controlled by the parameter θ), a transition occurs between a simple collective block motion and a granular-like surface flow regime.
