Emergence of Dissipation and Hysteresis From Interactions Among Reversible, Non-dissipative Units: The Case of Fluid-Fluid Interfaces
Holtzman, R., Dentz, M., Moura, M., Chubynsky, M., Planet, R., Ortin, J.
Fluid-fluid displacement is often irreversible—exhibiting hysteresis where reversal of the driving force (e.g. external pressure) does not reverse the fluids’ configuration. This irreversibility is linked to energy dissipation, a key to efficient design of engineering operations such as subsurface cleanup or energy storage. Here, we analyze (analytically, numerically and experimentally) a novel model system that exposes a striking phenomenon: emergence of hysteresis and dissipation in a system made of individually “reversible” (non-hysteretic) entities, due to their spatial interactions mediated by interfacial tension.
