Simulations show that the location of the counterforce on the fluid, not just the active monomer, determines whether an active polymer creates pusher or puller flow fields, and that stiff chains transmit forces in a way that can flip the expected flow type.

abstract
Polar polymer activity is a fundamental mechanism behind a large number of cellular dynamical processes. The number and location of the active sites on the polymer backbone play a central role in their dynamics and conformational properties. Globular conformations for high motor densities change to stretched ones for the more realistic moderate or low density of motors, with a self-propelled polymer velocity non-monotonically related to the motor density. A small difference in the position of the first motor, or the motor distribution, can also dramatically modify the polymer typical conformations

Locally tuned hydrodynamics of active polymer chains
Simulations show that the location of the counterforce on the fluid, not just the active monomer, determines whether an active polymer creates pusher or puller flow fields, and that stiff chains transmit forces in a way that can flip the expected flow type.
