Fluid Thread Patterns

Simulations and experiments show how the speed of a conveyor belt changes the patterns created when a fluid stream trickles onto the belt. 

Thin threads of fluids show how conveyor belt speeds control fluid pattern behavior in both experiments and models. A thin thread of viscous fluid (translucent threads at left) is poured onto a moving belt, creating a dazzling array of intricate patterns. Simulations (gold threads at right) reproduce this rich and complex behavior, confirming the accuracy of a theoretical model developed to describe the phenomenon.
