Phys. Rev. E 74, 041405 (2006) [7 pages]Bubble kinematics in a sheared foamReceived 6 July 2006; published 24 October 2006 We characterize the kinematics of bubbles in a sheared two-dimensional foam using statistical measures. We consider the distributions of both bubble velocities and displacements. The results are discussed in the context of the expected behavior for a thermal system and simulations of the bubble model. There is general agreement between the experiments and the simulation, but notable differences in the velocity distributions point to interesting elements of the sheared foam not captured by prevalent models. © 2006 The American Physical Society URL:
