@article{Balkovsky1999TurbulentDO, title={Turbulent dynamics of polymer solutions}, author={Balkovsky and Fouxon and Lebedev}, journal={Physical review letters}, year={1999}, volume={84 20}, pages={ 4765-8 } }
We study properties of dilute polymer solutions. The probability density function (PDF) of polymer end-to-end extensions R in turbulent flows is examined. We show that if the value of the Lyapunov exponent lambda is smaller than the inverse molecular relaxation time 1/tau then the PDF has a strong peak at the equilibrium size R0 and a power tail at R>>R0. This confirms and extends the results of J. L. Lumley [Symp. Math. 9, 315 (1972)]. There is no essential influence of polymers on the flow in…

In a spatially rough flow, the statistics of polymer stretching differs from that observed in laminar flows or in smooth chaotic flows, and the ability of the flow to stretch polymers weakens as the flow becomes rougher in space.

A rescaling analysis showed that most of the relaxation curves had a universal shape and their characteristic times (lambda t) increased as lambda t approximately L 1.65 +/- 0.13, in qualitative agreement with the theoretical prediction of dynamical scaling.
