Brochard-Wyart "stem-and-flower" model

The Brochard-Wyart "stem-and-flower" model posits that the relaxation of a tethered polymer under flow at intermediate velocities is described by

$L(t)-L_0 \propto \sqrt{\frac{kT}{\eta a} t}$

Where L(t) is the length at time t, $L_0$ is the initial length, k is the Boltzmann constant, T is the absolute temperature, $\eta$ is the viscosity of the solvent, and a is the persistence length.
