Abstract
In viscoelastic fluids, there is potential for instability mechanisms that persist even at negligibly low inertia: purely elastic instabilities. Some of these are well understood – including long-wave interfacial instabilities, and curved-streamline instabilities. However, some such instabilities are either predicted theoretically and never seen in experiments, or cause unexplained trouble in experiments.
I will present my experience with an instability that was an unfulfilled theoretical prediction for over a decade before being seen in experiment.
