In situ gelation in confined flow controls intermittent dynamics

Abstract:Polymer flows through pores, nozzles and other small channels govern both engineered and naturally occurring dynamics in many processes, from 3D printing to oil recovery in the earth's subsurface to a wide variety of biological flows. The crosslinking of polymers can change their material properties dramatically. In engineered flows, polymer crosslinking is often a situation to be avoided. For instance, in 3D printing it is greatly preferred for crosslinking to occur upon impact with a substrate rather than pr… Show more
