Abstract
We conduct numerical simulations on a simple model of a two-dimensional ste ady-state sheared foam, and define a quantity Gamma that measures stress fl uctuations in the constant-area system. This quantity reduces to the temper ature in an equilibrium system. Wie find that the relation between the visc osity and Gamma is the same as that between viscosity and temperature in a very different system, namely a supercooled liquid. This is the first evide nce of a common phenomenon linking these two systems.
