Continuous Pathway between the Elasto-Inertial and Elastic Turbulent States in Viscoelastic Channel Flow

Viscoelastic plane Poiseuille flow is shown to become linearly unstable in the absence of inertia, in the limit of high elasticities, for ultradilute polymer solutions. While inertialess elastic instabilities have been predicted for curvilinear shear flows, this is the first ever report of a purely...
