Analysis , Computations , and Experiments on Pinch - Off in Liquid Jets ( 05 frg 060 ) March 12 – 26 , 2005

This Focussed Research Group brought together a critical mass of researchers to work on fundamental problems that involve the breakup of liquid jets and on fluid and fluid jet problems that are motivated by industrial applications. Recent theoretical advances in the understanding of the breakup of single fluid jets are ripe to translate the control of breakup of jets. We also used concrete mathematical models to investigate utilizing liquid jet phenomena in the manufacture of microand nano-scale structures. Significant work remains to be done in the modeling and analysis of jets with more complicated geometries (e.g., compound jets) and involving complex fluids, which are typically found in industrial applications. The FRG included applied mathematicians involved in modelling and asymptotic analysis in fundamental problems (Papageorgiou, Siegel, Howell, Young) as well as more applied problems motivated by industrial applications (Huang, Miura, Wylie), and a physicist with expertise in modelling and numerical simulation (Zhang). Many of the program participants are internationally known for their contributions to interfacial fluid dynamics.
