We conduct numerical simulations on a simple model of a two-dimensional steady-state sheared foam, and define a quantity Γ that measures pressure fluctuations in the constant-area system. This quantity reduces to the temperature in an equilibrium system. We find that the relation between the viscosity and Γ is the same as the one between viscosity and temperature in a supercooled liquid. This is the first evidence of a common phenomenon linking these two very different systems.
