Hydrodynamic instabilities are encountered during the motion of non-Newtonian fluids at low flow rates and in the absence of inertia, buoyancy, and surface tension. These unexpected flow configurations, called elastic instabilities, do not arise in the corresponding flows of Newtonian fluids at the...
