Quasistatic simulations show that the topological changes or plastic events that occur when an aqueous foam flows are confined within narrow regions. The width of these regions is shown to scale with a power of the polydispersity in bubble area. The exponent is one‐half for linear Couette flow and one‐fifth for Poiseuille flow.
