FIG. 1.

Snapshots from a simulation with 80 000, ℓ/ = 1000, and = 1, showing the buckling instability at the stagnation points at cell corners.

FIG. 2.

Center-of-mass trajectories of polymers: (a)–(d) correspond to four different cell sizes at the same 20 000 and ℓ/ = 1000, each showing four different trajectories; (e) shows the case of a single polymer with = π and 20 000, but ℓ/ = 10 (enhanced online).

FIG. 3.

(a) Mean square displacement () of the filament center-of-mass as a function of time at 20 000 for three values of ℓ/, where the long-time behavior follows an approximate power law () ∝  . (b) Dependence of the exponent α on the reduced persistence length ℓ/. (c) Distribution of waiting times, defined as periods of time spent by a filament inside a given cell, in simulations with 20 000 and ℓ/ = 10.

FIG. 4.

(a) Frequency distribution of the magnitude of the center-of-mass velocity for various values of ℓ/ at 20 000. (b) Contours of the fluid velocity magnitude inside a given cell, indicating that the value of corresponds approximately to the largest ring of uniform velocity within the cell.

Probability distributions of mass of the polymer in a unit cell at 20 000 for different values of ℓ/. Probabilities are normalized to be unity for a uniform distribution.
