Transition to elasto-inertial Taylor-Couette turbulence in viscoelastic, shear-thinning polymer solution —Tom Lacassagne, University College London

In non-Newtonian polymer solutions, the flow between two concentric cylinders with the inner rotating (Taylor-Couette flow) transitions from azimuthal Couette flow to elasto-inertial turbulence, through various intermediate unsteady flow states. The transitions are visualised using reflective mica particles and high speed imaging (figure in false colour).
