Featured ResearchYuriko Renardy -Mixtures of two liquids arise in many industrial applications, such as the production of incompatible polymer blends for recycling plastics. Typically, one of the molten polymers disperses as droplets in the other, and larger drops break up into smaller ones. Experimental studies show that the drop rupturing phenomenon and the resulting microstructure is sensitive to the physical properties of the fluid pairs, and this in turn has direct bearance on the quality of the final blend. Computational studies of the deformation and breakup behavior of a single droplet in a well-defined flow field are paradigms of theoretical investigations for immiscible polymer blends. The movie shows direct numerical simulation of microconfined droplet breakup to monodisperse satellites. Funded by NSF-DMS, computational resources through NCSA teragrid and VT-ARC.
