Perspectives on viscoelastic flow instabilities and elastic turbulence

Viscoelastic fluids can exhibit striking flow instabilities under conditions where ordinary Newtonian are stable, owing to the nonlinear coupling of elastic and viscous stresses. This article provides perspectives on viscoelastic by integrating input from speakers at a recent international workshop: historical remarks, characterization flows, discussion experimental simulation tools, modern questions puzzles that motivate further studies this fascinating subject. The materials here will be useful for researchers educators alike, especially as subject continues evolve in both fundamental understanding applications engineering sciences.
