Flow Direction-Dependent Elastic Instability in a Symmetry-Breaking Microchannel

Flow Direction-Dependent Elastic Instability in a Symmetry-Breaking Microchannel

This paper reports flow direction-dependent elastic instability in a symmetry-breaking microchannel. The microchannel consisted of a square chamber and a nozzle structure. A viscoelastic polyacrylamide solution was used for the instability demonstration. The instability was realized as the viscoelas...
