Viscoelastic flow transitions in abrupt planar contractions
Lars Geneiser, Arvind Gopinath, Robert Armstrong +1
We present experimental evidence of global viscoelastic flow transitions in 2:1, 8:1 and 32:1 planar contractions under inertia-less conditions. Light sheet visualization and laser…

Transitions to Nematic states in homogeneous suspensions of high aspect ratio magnetic rods
A. Gopinath, L. Mahadevan, R. C. Armstrong
Isotropic-Nematic and Nematic-Nematic transitions from a homogeneous base state of a suspension of high aspect ratio, rod-like magnetic particles are studied for both Maier-Saupe a…
