Relaminarization of elastic turbulence

Elastic stress in viscoelastic flows, at vanishing inertia, can give rise to elastic instabilities and turbulence (ET), causing an increased frictional drag. Here we show that the measured drag correlates well with waves intensity wall-normal vorticity above onset of ET. Further, demonstrate increasing frequency Weissenberg number (Wi) results their strong attenuation hinders ET growth thereby reduction. Thus, this suggests a possible mechanism interaction fluctuations, leading reduction relaminarization phenomena low-Re.
