Phys. Rev. Lett. 78, 2485–2488 (1997)Experimental Studies of Bubble Dynamics in a Slowly Driven Monolayer FoamReceived 18 November 1996; published in the issue dated 24 March 1997 We report a study of the topological rearrangements in a Langmuir-monolayer foam subjected to a constant rate of strain. Measurements of the size distribution for the rearrangements are compared with three simulations that find a power-law distribution for a gas area fraction φ = 1, a power law for φ = 0.84, and an exponential cutoff in the size distribution. No evidence for power-law scaling is found in the experiments for 0.85≤φ≤0.95. These comparisons suggest that the nature of the dissipative mechanisms is an important factor in the determination of the size distribution. © 1997 The American Physical Society URL:
