Interacting loop models explain the flows of active fluids in hydraulic networks

Predicting the complex flows that emerge in active fluid networks remains a challenge. A combination of experiments and theory was used to determine the hydraulic laws of active fluids. Analogies with frustrated magnetism and loop models explain the emergent flow patterns that result when active fluids explore pipe networks.
